Jason Lowe commented on MAPREDUCE-6618: --------------------------------------- Patch looks better, thanks! What about the client cache that's also in YARNRunner? It potentially has a history server client that I think also should be closed in this case. > YarnClientProtocolProvider leaking the YarnClient thread. > ---------------------------------------------------------- > > Key: MAPREDUCE-6618 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6618 > Project: Hadoop Map/Reduce > Issue Type: Bug > Reporter: Xuan Gong > Assignee: Xuan Gong > Attachments: MAPREDUCE-6618.1.patch, MAPREDUCE-6618.2.patch > > > YarnClientProtocolProvider creates YarnRunner which includes > ResourceMgrDelegate.
