Subject [jira] [Commented] (HADOOP-15028) Got errors while running org.apache.hadoop.io.TestSequenceFileAppend
Date Wed, 15 Nov 2017 13:42:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16253452#comment-16253452

Steve Loughran commented on HADOOP-15028:
-----------------------------------------

Given it works in 2.6.5. I don't think anyone is going to worry about this test not working
in 2.6.4. The response is going to be "does if you away if you move to a later version", and
if it does, one of "cannot reproduce/wonfix" will be applied. The way to fix it would be to
identify the specific patches which fixed the test and then cherry pick them into some 2.6.4.x
branch...but we don't do releases at that granuarlty. I

Unless you have some reason to stick to 2.6.4, upgrade. If you must stick to 2.6.4,  in production,
I'd recommend tracking down which changed fixed things and deciding whether you want to: backport,
retest and roll out.
