> We need to add the heap dump option for:
> - All Hive services (Hive1/HiveServer2, Hive2/HiveServer2 and Metastore):
> {code}
> -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=<'/tmp/' by default or
> 'Configurable location provided'>
> {code}
> option appended to "Advance hive-env" -> hive-env-template ->
> HADOOP_CLIENT_OPTS environment variable
> - HSI YARN jobs:
> {code}
> -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=<'/tmp/' by default or
> 'Configurable location provided'>
> {code}
> option added to "Advanced hive-interactive-env" -> Llap app java opts. Logs
> will be generated at: /<'Configurable location
> provided'>/java_<pid-of-llap-daemon>.hprof on the nodes that failed with OOM.
> - Tez component:
> {code}
> -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=<'/tmp/' by default or
> 'Configurable location provided'>
> {code}
> option added to tez.am.launch.cmd-opts for AM OOM and
> tez.task.launch.cmd-opts for task OOM.
> *>>>>* 'Configurable location provided' should be one config where user can
> change the location and consumable by all others.
> Further, whether to keep the heap dump option ENABLED or DISABLED should be
> configurable via Ambari. [~carter] to confirm for this. By default, option
> should be DISABLED.
> *>>>>* ENABLING/DISABLING of option will require the above components
> RESATARt for change to take effect.
> *>>>>* permissions for dump file can be 600 for <hive user>:<hive group>.
