Subject [jira] [Commented] (HADOOP-13388) Clean up TestLocalFileSystemPermission
Date Thu, 18 Aug 2016 16:27:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426746#comment-15426746

Andras Bokor commented on HADOOP-13388:

Thanks for the review [~anu] and [~liuml07].

# The import changes was done by my IDE. The Assert got wildcard when I imported assertFalse.
I think wildcard is reasonable there since assertFalse the 4th method from the class
# I thought assertFalse is more readable here because we have an asserTrue followed by a delete
so assertFalse seemed more straightforward.
# Good point. I put them into the try. I had to add some null check to the {{cleanup}} method
because if we have an exception while creating the file the cleanup will throw NPE which will
hide the real exception.
# Yes, I do not really understand the purpose of that check. {{getGroups}} cannot return with
null and on Unix users have to belong to at least one group. I would remove the whole block.

# Yes, the order was wrong. Fixed.
# Please check 4th point from above
# Replacing for by while only has readability purposes. While seems more appropriate here
for me (Idea also suggests to do).

What do you guys think about the 2nd patch?
