Subject [jira] [Commented] (HDFS-6588) Investigating removing getTrueCause method in Server.java
Date Sun, 20 Jul 2014 16:12:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14067968#comment-14067968
] 

Yongjun Zhang commented on HDFS-6588:
-------------------------------------

The symlink tests failed three times in a row here, which indicates that something is wrong.
I filed HDFS-6707, investigated and found root cause (irrelevant to the patch of HDFS-6588),
posted patch there pending review.  The other tests failed here appear to be flaky, but will
try a run again once HDFS-6707 fix is committed.

> What I'm saying is I think the patch adds too much unnecessary code. Filing an improvement
to delete all but a few lines of the code changed in this patch seems a bit odd. I think you
just need to:
> - Delete getTrueCause entirely instead of moving it elsewhere
> - In saslProcess, just throw the exception instead of running it through getTrueCause
since it's not a "InvalidToken wrapping another exception" anymore.
> - Keep your 3-line change to unwrap SecurityException in toResponse
> {quote}
> There are multiple test failures, after making the suggested changes, Filing this jira
to dedicate to the investigation of removing getTrueCause method.
> More detail will be put in the first comment.
