Subject [jira] [Commented] (HDFS-5515) Fix TestDFSStartupVersions for HDFS-2832
Date Fri, 15 Nov 2013 01:37:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13823193#comment-13823193
] 

Junping Du commented on HDFS-5515:
----------------------------------

+1 patch looks good. I think #1 fix the TestDFSStartupVersions failure which due to creating
different datanodeUuids in every iteration but shutdownDatanodes don't wipe it from DatanodeManager.
I was trying to adding wipe nodes after shutdownDatanode() but patch here looks better.

> The test runs multiple iterations of Datanode storage layout but appears to have some
dependencies between iterations. Filing a Jira to investigate and fix.
