Debugging Hadoop is ... tricky. Most likely the parameter you are passing (es.version) is incorrect - there's no such
Elasticsearch version.
2.1.0.Beta3 is the connector, es-hadoop version. es.version indicates the
version of Elasticsearch itself.
My advice is to first start with basic steps and defaults as described in the
docs [1].
As for the debug part itself, you have to look into your node/cluster logs, in particular the yarn/node ones to see the
underlying container exception.
Whatever message/exception is thrown by the underlying container, it does not bubble up (it is always wrapped by YARN
itself) and thus one has to manually
track it down...

Hi all,
HDFS 2.6.0.2.2.0.0 Apache Hadoop Distributed File System
Es-Hadoop : 2.1.0.Beta3
OS : Centos 6
When i start elasticsearch (hadoop jar elasticsearch-yarn-2.1.0.Beta3.jar
-start es.version=2.1.0.Beta3), the
process end FINISHED/FAILED and the only log i found is :
2015-03-31 13:29:57,792 INFO nodemanager.ContainerExecutor
(ContainerExecutor.java:logOutput(283)) - at
java.lang.Thread.run(Thread.java:744)
2015-03-31 13:29:57,793 WARN launcher.ContainerLaunch
(ContainerLaunch.java:call(338)) - Container exited with a
non-zero exit code 127
No ERROR log only WARN...
Can'i set the logger in DEBUG mode (how) ?
Are there any other log files ?
Thank
Stephane
