Subject [jira] [Commented] (HDFS-6719) org.apache.hadoop.fs.TestDFVariations.testMount failed intermittently because specified path doesn't exist
Date Wed, 23 Jul 2014 18:13:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14072061#comment-14072061
] 

Arpit Agarwal commented on HDFS-6719:
-------------------------------------

Nitpick, test_root need not be static. Also if you post another patch you could consider just
using the full test name for the directory instead of testdfv.

+1 with that fixed.

Separately we can check other tests for misuse of test.build.data. Quick grep gave the following:
