Subject [jira] [Commented] (HDFS-2700) TestDataNodeMultipleRegistrations is failing in trunk
Date Sat, 17 Dec 2011 17:45:30 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13171616#comment-13171616
] 

Uma Maheswara Rao G commented on HDFS-2700:
-------------------------------------------

Here the problem is DatanodeProtocolClientSideTranslatorPB is not proxy instance directly.
This is wrapper around the proxy instance of DatanodeProtocolPB.

So, shutting down the previos cluster, the clinets are not getting cleared and they will be
cached. When new cluster starts it may get old invalid clients and getting EOFEceptions.

So, we should just call close of DatanodeProtocolClientSideTranslatorPB. That will call the
RPC.stopProxy by passing the real proxy instance (DatanodeProtocolPB).

Attached the patch by closing the DatanodeProtocolClientSideTranslatorPB.


Thanks
Uma
