Subject [jira] [Created] (HBASE-11565) Stale connection could stay for a while
Date Tue, 22 Jul 2014 16:26:41 GMT
Jimmy Xiang created HBASE-11565:

             Summary: Stale connection could stay for a while
                 Key: HBASE-11565
                 URL: https://issues.apache.org/jira/browse/HBASE-11565
             Project: HBase
          Issue Type: Bug
          Components: Client
            Reporter: Jimmy Xiang

In RpcClient, we cache the connection to each region server. When the connection goes bad,
it stays in the cache till it's removed. Before it's removed, new calls will try to use it
and just fail. The connection is a thread. It could be stuck in trying to receive some response.
Before this receiving thread times out, it won't remove itself from the cache.

It will be better to interrupt the receiving thread and let it clean up sooner.
