Requirements

editBefore using Elasticsearch on YARN, please pay attention to the requirements below - ignoring them can lead to abnormal behavior, error and ultimately a poor experience and data loss.
make sure to verify all nodes in a cluster when checking the version of a certain artifact.
YARN
editA YARN environment running on Hadoop 2.4 (or higher) is recommended. This can be easily checked by verifying the Hadoop version installed on the target nodes:
$ hadoop version Hadoop 2.4.1 Subversion http://svn.apache.org/repos/asf/hadoop/common -r 1604318 Compiled by jenkins on 2014-06-21T05:43Z Compiled with protoc 2.5.0 From source with checksum bb7ac0a3c73dc131f4844b873c74b630 This command was run using /opt/share/hadoop/common/hadoop-common-2.4.1.jar
For Hadoop distros, check the base core YARN/Hadoop version and make sure it is 2.4 compatible.

Elasticsearch
editElasticsearch on YARN uses the same requirements on Elasticsearch as elasticsearch-hadoop - in other words, using the latest stable Elasticsearch is highly recommended for both stability and performance reasons.
