Subject [jira] [Commented] (HDFS-5132) Deadlock in namenode while running load generator with 15 threads
Date Tue, 27 Aug 2013 18:02:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13751509#comment-13751509

Jing Zhao commented on HDFS-5132:
---------------------------------

[~kihwal], I think you are right. Currently all the safemode related checks are done under
the FSN r/w lock (except getBlockLocations). Since you already have the fix, could you upload
a patch? Thanks!
