Subject [jira] [Commented] (HDFS-11025) TestDiskspaceQuotaUpdate fails in trunk
Date Tue, 18 Oct 2016 16:41:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15585943#comment-15585943

Erik Krogen commented on HDFS-11025:
------------------------------------

Agreed, shouldn't be necessary to keep the same port across the restarts. Thanks [~linyiqun]
for catching and fixing this and [~ebadger] for taking a look.

> The test {{TestDiskspaceQuotaUpdate}} fails sometimes after HDFS-10843, the link addresse:
https://builds.apache.org/job/PreCommit-HDFS-Build/17200/testReport/. The stack infos:
> {code} 
> java.net.BindException: Problem binding to [localhost:49195] java.net.BindException:
Address already in use; For more details see:  http://wiki.apache.org/hadoop/BindException
> {code} 
> I found the bind exception was happened in new test method {{TestDiskspaceQuotaUpdate.testQuotaIssuesWhileCommitting}}.
The related codes:
> {code}
>   public void testQuotaIssuesWhileCommitting() throws Exception {
>     ...
>     try {
>       for (int i = REPLICATION - 1; i > 0; i--) {
>         dnprops.add(cluster.stopDataNode(i));
>       }
>       ...
>     } finally {
>       for (MiniDFSCluster.DataNodeProperties dnprop : dnprops) {
>         cluster.restartDataNode(dnprop, true);
>       }
>       cluster.waitActive();
>     }
>   }
> {code}
> I think we can make a simple fix in {{cluster.restartDataNode(dnprop, true);}}. The tests
in {{TestDiskspaceQuotaUpdate}} just care about that if the cluster is up and running. So
I think this change will not influence the current logic,
