Subject [jira] [Commented] (HDFS-9716) o.a.h.hdfs.TestRecoverStripedFile fails intermittently in trunk
Date Tue, 02 Feb 2016 09:14:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15127941#comment-15127941

Kai Zheng commented on HDFS-9716:

Thanks [~liuml07] for reporting this and [~walter.k.su] to work on this. I also noted the
failure while working on HDFS-9719 but then never got the chance again.

To fix it, we would need to reliably repeat the issue, but given current test approach, it
may be not easy. It looks related to mis-aligned decoding input buffers given. To expose the
issue, I guess we can reorganize the tests by: 1) define all sorts of file lengths to test;
2) for each kind of file length, test the current supported block corrupting cases with the
randomness. The test space will be much extended and can cover much more. Sure it will mean
more test time to take.

Walter, what do you think?
