Andras Bokor commented on HDFS-10270:
-------------------------------------
Hi [~kihwal],
We do not see the value to check NumOpenConnections since it can cause
intermittent failures and with the other checks the JMX metrics are tested
enough. Our suggestion is to remove NumOpenConnections check. Do you see any
disadvantages removing NumOpenConnections check?
> TestJMXGet:testNameNode() fails
> -------------------------------
>
> Key: HDFS-10270
> URL: https://issues.apache.org/jira/browse/HDFS-10270
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 3.0.0, 2.8.0
> Reporter: Andras Bokor
> Assignee: Gergely Novák
> Priority: Minor
> Attachments: HDFS-10270.001.patch, TestJMXGet.log, TestJMXGetFails.log
>
>
> 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]).
