-----------------------------------------
Summary: TezClient and TezSession doesn't stops/close YarnClient
Key: MAPREDUCE-5921
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5921
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Subroto Sanyal
The _org.apache.tez.client.TezClient_ creates a
_org.apache.hadoop.yarn.client.api.YarnClient_ to submit an DAG application to
cluster but, no apis exist to stop/close the
org.apache.hadoop.yarn.client.api.YarnClient object residing inside.
Same is the case with _org.apache.tez.client.TezSession_ which doesn't close
the _org.apache.hadoop.yarn.client.api.YarnClient_ object in stop() call.
>From [~sseth]:
{quote}I think this is just an oversight. The YarnClient created by the
TezClient
could also be shared with the DAGClient that is returned after submitting
an application. Eventually, the connection will end up timing out at the
RPC level.{quote}
