Subject [jira] [Commented] (HDFS-4315) DNs with multiple BPs can have BPOfferServices fail to start due to unsynchronized map access
Date Mon, 17 Dec 2012 07:52:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13533717#comment-13533717
] 

Aaron T. Myers commented on HDFS-4315:
--------------------------------------

I looped this test 5923 times for about 50 hours and it never failed. I'm going to conclude
based on this that this patch fixes the issue.

I'm going to commit this momentarily.

> In some nightly test runs we've seen pretty frequent failures of TestWebHdfsWithMultipleNameNodes.
I've traced the root cause to an unsynchronized map access in the DataStorage class.
