Subject [jira] Commented: (HDFS-1170) Add more assertions to TestLargeDirectoryDelete
Date Mon, 14 Jun 2010 23:46:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12878801#action_12878801

Tom White commented on HDFS-1170:
---------------------------------

+1

I think this can be committed (to 0.21 and trunk). I ran TestLargeDirectoryDelete 10 times
and got 8 NullPointerExceptions. With this patch I got no failures and no NPEs in 10 runs,
so it fixes HDFS-1170 for me (this is on a Mac).
