Subject [jira] [Commented] (HADOOP-12464) Interrupted client may try to fail-over and retry
Date Thu, 08 Oct 2015 12:45:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14948605#comment-14948605

Steve Loughran commented on HADOOP-12464:
-----------------------------------------

Linking to the issues I've seen with hanging on shutdown. Do these stack traces match what
you've seen?

We could have a test for this BTW: find a free port, create an hdfs client of hdfs://localhost/$port,
try to use it and then try to shut down the FS

> When an IPC client is interrupted, it sometimes try to fail-over to a different namenode
and retry.  We've seen this causing hang during shutdown.
