Subject RE: How to handle Container crash in YARN

Sajid,

Check the logs for your container at $HADOOP_INSTALL_DIR/logs/userlogs/<application_id>/<container_id>.
Note that these will be present on the node where your Application Master is running.

If the container was not able to start, you might get something by printing the stack trace
in onStartContainerError(ContainerId containerId, Throwable t) callback method in the NMClientAsync.CallbackHandler
interface.

You should always be capturing the exit status of the container inside onContainersCompleted(List<ContainerStatus>
completedContainers) callback method of AMRMClientAsync.CallbackHandler interface.

Please see the source of Distributed Shell application on github for an example of how this
is done - https://github.com/apache/hadoop-common/tree/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-distributedshell/src/main/java/org/apache/hadoop/yarn/applications/distributedshell

Regards,
Rahul Chhiber
