    • (default 60000) -- HRegion server lease period in milliseconds. Default is 60 seconds. Clients must report in within this period else they are considered dead.
  • [:hbase][:regionserver][:handler_count] - (default: "10")
    • hbase.regionserver.handler.count (default 10) -- Count of RPC Server instances spun up on RegionServers. Same property is used by the Master for count of master handlers.
  • [:hbase][:regionserver][:split_limit] - (default: "2147483647")
    • hbase.regionserver.regionSplitLimit (default 2147483647) -- Limit for the number of regions after which no more region splitting should take place. This is not a hard limit for the number of regions but acts as a guideline for the regionserver to stop splitting after a certain limit. Default is set to MAX_INT; i.e. do not block splitting.

  • [:hbase][:regionserver][:worker_period] - (default: "10000")
    • hbase.server.thread.wakefrequency (default 10_000) -- Time to sleep in between searches for work (in milliseconds). Used as sleep interval by service threads such as log roller.
  • [:hbase][:regionserver][:balancer_period] - (default: "300000")
    • hbase.balancer.period (default 300000) -- Period at which the region balancer runs in the Master.
  • [:hbase][:regionserver][:balancer_slop] - (default: "0")
    • hbase.regions.slop (default 0) -- Rebalance if any regionserver has more than average + (average * slop) regions
  • [:hbase][:regionserver][:max_filesize] - (default: "268435456")
    • hbase.hregion.max.filesize (default 268435456) -- Maximum HStoreFile size. If any one of a column families' HStoreFiles has grown to exceed this value, the hosting HRegion is split in two.
  • [:hbase][:regionserver][:hfile_block_size] - (default: "65536")
    • hbase.mapreduce.hfileoutputformat.blocksize (default 65536) -- The mapreduce HFileOutputFormat writes storefiles/hfiles. This is the minimum hfile blocksize to emit. Usually in hbase, writing hfiles, the blocksize is gotten from the table schema (HColumnDescriptor) but in the mapreduce outputformat context, we don't have access to the schema so get blocksize from Configuation. The smaller you make the blocksize, the bigger your index and the less you fetch on a random-access. Set the blocksize down if you have small cells and want faster random-access of individual cells.
  • [:hbase][:regionserver][:required_codecs] -
    • hbase.regionserver.codecs (default "") -- To have a RegionServer test a set of codecs and fail-to-start if any code is missing or misinstalled, add the configuration hbase.regionserver.codecs to your hbase-site.xml with a value of codecs to test on startup. For example if the hbase.regionserver.codecs value is "lzo,gz" and if lzo is not present or improperly installed, the misconfigured RegionServer will fail to start.
  • [:hbase][:regionserver][:block_cache_size] - (default: "0.2")
    • hfile.block.cache.size (default 0.2) -- Percentage of maximum heap (-Xmx setting) to allocate to block cache used by HFile/StoreFile. Default of 0.2 means allocate 20%. Set to 0 to disable.
  • [:hbase][:regionserver][:hash_type] - (default: "murmur")
    • hbase.hash.type (default murmur) -- The hashing algorithm for use in HashFunction. Two values are supported now: murmur (MurmurHash) and jenkins (JenkinsHash). Used by bloom filters.
  • [:hbase][:stargate][:run_state] - (default: "start")
  • [:hbase][:stargate][:port] - (default: "8080")
  • [:hbase][:stargate][:jmx_dash_port] - (default: "10105")
  • [:hbase][:stargate][:readonly] -
    • (default false) -- Defines the mode the REST server will be started in. Possible values are: false: All HTTP methods are permitted - GET/PUT/POST/DELETE. true: Only the GET method is permitted.
  • [:hbase][:thrift][:run_state] - (default: "start")
  • [:hbase][:thrift][:jmx_dash_port] - (default: "10104")
  • [:hbase][:zookeeper][:jmx_dash_port] - (default: "10103")
  • [:hbase][:zookeeper][:peer_port] - (default: "2888")
  • [:hbase][:zookeeper][:leader_port] - (default: "3888")
  • [:hbase][:zookeeper][:client_port] - (default: "2181")
  • [:hbase][:zookeeper][:session_timeout] - (default: "180000")
  • [:hbase][:zookeeper][:znode_parent] - (default: "/hbase")
    • zookeeper.znode.parent (default "/hbase") -- Root ZNode for HBase in ZooKeeper. All of HBase's ZooKeeper files that are configured with a relative path will go under this node. By default, all of HBase's ZooKeeper file path are configured with a relative path, so they will all go under this directory unless changed.
  • [:hbase][:zookeeper][:znode_rootserver] - (default: "root-region-server")
    • zookeeper.znode.rootserver (default root-region-server) -- Path to ZNode holding root region location. This is written by the master and read by clients and region servers. If a relative path is given, the parent folder will be ${zookeeper.znode.parent}. By default, this means the root location is stored at /hbase/root-region-server.
  • [:hbase][:zookeeper][:max_client_connections] - (default: "2000")
    • (default 2000) -- Limit on number of concurrent connections (at the socket level) that a single client, identified by IP address, may make to a single member of the ZooKeeper ensemble. Set high to avoid zk connection issues running standalone and pseudo-distributed.
  • [:hbase][:client][:write_buffer] - (default: "2097152")
    • hbase.client.write.buffer (default 2097152) Default size of the HTable client write buffer in bytes. A bigger buffer takes more memory -- on both the client and server side since server instantiates the passed write buffer to process it -- but a larger buffer size reduces the number of RPCs made. For an estimate of server-side memory-used, evaluate hbase.client.write.buffer * hbase.regionserver.handler.count
  • [:hbase][:client][:pause_period_ms] - (default: "1000")
    • hbase.client.pause (default 1000) -- General client pause value. Used mostly as value to wait before running a retry of a failed get, region lookup, etc.
  • [:hbase][:client][:retry_count] - (default: "10")
    • hbase.client.retries.number (default 10) -- Maximum retries. Used as maximum for all retryable operations such as fetching of the root region from root region server, getting a cell's value, starting a row update, etc.
  • [:hbase][:client][:scanner_prefetch_rows] - (default: "1")
    • hbase.client.scanner.caching (default 1) -- Number of rows that will be fetched when calling next on a scanner if it is not served from (local, client) memory. Higher caching values will enable faster scanners but will eat up more memory and some calls of next may take longer and longer times when the cache is empty. Do not set this value such that the time between invocations is greater than the scanner timeout; i.e.
  • [:hbase][:client][:max_keyvalue_size] - (default: "10485760")
    • hbase.client.keyvalue.maxsize (default 10485760) -- Specifies the combined maximum allowed size of a KeyValue instance. This is to set an upper boundary for a single entry saved in a storage file. Since they cannot be split it helps avoiding that a region cannot be split any further because the data is too large. It seems wise to set this to a fraction of the maximum region size. Setting it to zero or less disables the check.
  • [:hbase][:memstore][:flush_upper_heap_pct] - (default: "0.4")
    • (default 0.4) -- Maximum size of all memstores in a region server before new updates are blocked and flushes are forced. Defaults to 40% of heap
  • [:hbase][:memstore][:flush_lower_heap_pct] - (default: "0.35")
    • (default 0.35) -- When memstores are being forced to flush to make room in memory, keep flushing until we hit this mark. Defaults to 35% of heap. This value equal to causes the minimum possible flushing to occur when updates are blocked due to memstore limiting.
  • [:hbase][:memstore][:flush_size_trigger] - (default: "67108864")
    • hbase.hregion.memstore.flush.size (default 67108864) -- Memstore will be flushed to disk if size of the memstore exceeds this number of bytes. Value is checked by a thread that runs every hbase.server.thread.wakefrequency.
  • [:hbase][:memstore][:preflush_trigger] - (default: "5242880")
    • hbase.hregion.preclose.flush.size (default 5 mb) -- If the memstores in a region are this size or larger when we go to close, run a "pre-flush" to clear out memstores before we put up the region closed flag and take the region offline. On close, a flush is run under the close flag to empty memory. During this time the region is offline and we are not taking on any writes. If the memstore content is large, this flush could take a long time to complete. The preflush is meant to clean out the bulk of the memstore before putting up the close flag and taking the region offline so the flush that runs under the close flag has little to do.
  • [:hbase][:memstore][:flush_stall_trigger] - (default: "8")
    • hbase.hregion.memstore.block.multiplier (default 2) -- Block updates if memstore has hbase.hregion.block.memstore time hbase.hregion.flush.size bytes. Useful preventing runaway memstore during spikes in update traffic. Without an upper-bound, memstore fills such that when it flushes the resultant flush files take a long time to compact or split, or worse, we OOME.
  • [:hbase][:memstore][:mslab_enabled] -
    • hbase.hregion.memstore.mslab.enabled (default false) -- Experimental: Enables the MemStore-Local Allocation Buffer, a feature which works to prevent heap fragmentation under heavy write loads. This can reduce the frequency of stop-the-world GC pauses on large heaps.
  • [:hbase][:compaction][:files_trigger] - (default: "3")
    • hbase.hstore.compactionThreshold (default 3) -- If more than this number of HStoreFiles in any one HStore (one HStoreFile is written per flush of memstore) then a compaction is run to rewrite all HStoreFiles files as one. Larger numbers put off compaction but when it runs, it takes longer to complete.
  • [:hbase][:compaction][:pause_trigger] - (default: "7")
    • hbase.hstore.blockingStoreFiles (default 7) -- If more than this number of StoreFiles in any one Store (one StoreFile is written per flush of MemStore) then updates are blocked for this HRegion until a compaction is completed, or until hbase.hstore.blockingWaitTime has been exceeded.
  • [:hbase][:compaction][:pause_time] - (default: "90000")
    • hbase.hstore.blockingWaitTime (default 90_000) -- The time an HRegion will block updates for after hitting the StoreFile limit defined by hbase.hstore.blockingStoreFiles. After this time has elapsed, the HRegion will stop blocking updates even if a compaction has not been completed. Default: 90 seconds.
  • [:hbase][:compaction][:max_combine_files] - (default: "10")
    • hbase.hstore.compaction.max (default 10) -- Max number of HStoreFiles to compact per 'minor' compaction.
  • [:hbase][:compaction][:period] - (default: "86400000")
    • hbase.hregion.majorcompaction (default 86400000) -- The time (in miliseconds) between 'major' compactions of all HStoreFiles in a region. Default: 1 day. Set to 0 to disable automated major compactions.
  • [:users][:hbase][:uid] - (default: "304")
  • [:tuning][:ulimit][:hbase] -
