Subject [jira] [Commented] (HDFS-2720) HA : TestStandbyIsHot is failing while copying in_use.lock file from NN1 nameSpaceDirs to NN2 nameSpaceDirs
Date Thu, 29 Dec 2011 22:40:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13177434#comment-13177434
] 

Todd Lipcon commented on HDFS-2720:
-----------------------------------

That would be a nice improvement... but I think it makes sense to do this small fix that Uma
proposed so the tests run on Windows, and then do the "standby initialize from remote active"
feature separately?

> To maintain the clusterID same , we are copying the namespaceDirs from 1st NN to other
NNs.
> While copying this files, in_use.lock file may not allow to copy in all the OSs since
it has aquired the lock on it.
