Subject [jira] [Commented] (HDFS-10270) TestJMXGet:testNameNode() fails
Date Tue, 12 Apr 2016 07:57:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10270?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15236790#comment-15236790
] 

Gergely Novák commented on HDFS-10270:
--------------------------------------

So [~kihwal], are you suggesting to have a wait/assert for checking if the number of connections
is equal to 2 (datanode, client)? And to fulfil this to increase the ipc client idle timeout?

If so, can you (or the original author of the test) explain why we need to test if the client
is still connected?

> It fails with java.util.concurrent.TimeoutException. Actually the problem here is that
we expect 2 as NumOpenConnections metric but it is only 1. So the test waits 60 sec then fails.
> Please find maven output so the stack trace attached ([^TestJMXGetFails.log]).
