flume chef cookbook

Installs/Configures flume

Overview

Cookbook to install flume on a cluster.

Use flume::master to set up a master node. Use flume::node to set up a
physical node. Currently only one physical node per machines.

Configure logical nodes with the logical_node resource - see the test_flow.rb
recipe for an example. This is still somewhat experimental, and some features
will not work as well as they should until chef version 0.9.14 and others until
the next release of flume.

Coming soon flume::xxx_plugin.

Notes

This recipe relies on cluster_discovery_services to determine which nodes
across the cluster act as flume masters, and which nodes provide zookeeper
servers.

Attributes

• [:flume][:aws_access_key] - AWS access key used for writing to s3 buckets
• [:flume][:aws_secret_key] - AWS secret key used for writing to s3 buckets
• [:flume][:cluster_name] - (default: "cluster_name")
  • The name of the cluster to participate with (masters and zookeepers...)
• [:flume][:plugins] - Hash for plugin configuration
  • If you have a particular plugin to configure, you can also configure the classpath and the classes to include in the configuration file with attributes in the following forms: node[:flume][:plugin][{plugin_name}][:classes] node[:flume][:plugin][{plugin_name}][:classpath] node[:flume][:plugin][{plugin_name}][:java_opts]
• [:flume][:classes] -
• [:flume][:classpath] - list of directories and jars to add to the FLUME_CLASSPATH
• [:flume][:java_opts] - list of command line parameters to add to the jvm
• [:flume][:collector] - Format of node's logs
  • output_format -- Controls what format the node writes logs (using collectorSink):
  • avro - Avro Native file format. Default currently is uncompressed.
  • avrodata - Binary encoded data written in the avro binary format.
  • avrojson - JSON encoded data generated by avro.
  • default - a debugging format.
  • json - JSON encoded data.
  • log4j - a log4j pattern similar to that used by CDH output pattern.
  • raw - Event body only. This is most similar to copying a file but does not preserve any uniqifying metadata like host/timestamp/nanos.
  • syslog - a syslog like text output format.

codec -- Controls what kind of compression the collector will use when writing a file.
whether or not collected logs are gzipped before writing
them to their final resting place (using collectorSink)
* GZipCodec
* BZip2Codec

• [:flume][:data_dir] - Directory for local in-transit files (default: "/data/db/flume")
• [:flume][:home_dir] - (default: "/usr/lib/flume")
• [:flume][:conf_dir] - (default: "/etc/flume/conf")
• [:flume][:log_dir] - (default: "/var/log/flume")
• [:flume][:pid_dir] - (default: "/var/run/flume")
• [:flume][:master][:external_zookeeper] - Use External Zookeeper?
  • false to use flume's zookeeper. True to attach to an external zookeeper.
• [:flume][:master][:zookeeper_port] - port to talk to zookeeper on (for external zookeeper) (default: "2181")
• [:flume][:master][:run_state] - (default: "stop")
• [:flume][:node][:run_state] - (default: "stop")
