Subject [jira] [Commented] (HDFS-8690) LeaseRenewer should not abort DFSClient when renew fails
Date Mon, 29 Jun 2015 17:32:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14605945#comment-14605945

Arpit Agarwal commented on HDFS-8690:

+1 pending Jenkins. I agree that the special case for SocketTimeoutException looks incorrect.

I tried to lookup the history but was not able to get past the source tree re-org in 2011.
I will hold off committing in case someone more familiar with the history of this behavior
wants to comment.

Thanks for reporting it and submitting the patch [~lichangleo].

> The lease renewer special cases SocketTimeoutExceptions to abort the DFSClient.  Aborting
causes the client to be permanently unusable, which causes filesystem instances to stop working.
 All other IOExceptions do not abort.  The special case should be removed and/or abort should
not completely shutdown the proxy.
