Subject [jira] [Commented] (HDFS-9732) Improve DelegationTokenIdentifier.toString() for better logging
Date Tue, 17 May 2016 21:19:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15287588#comment-15287588

Yongjun Zhang commented on HDFS-9732:

Thanks [~steve_l], [~cnauroth] and [~aw] again!

I just committed to trunk.

I attempted to cherry-pick to branch-2 etc, and found that there are quite a few conflicts.
 Then, I found that one dependent jira is incompatible itself and thus not made its path to
branch-2, See:


Even if I get this to branch-2, I found there is still some other missing jiras in branch-2
that makes it unclean. The test I used in TestDelegationTokenFetcher doesn't exist in branch-2.

At this point, I decide to get it to trunk only, since we are working on 3.0 anyways.

>   Original Estimate: 0.5h
>  Remaining Estimate: 0.5h
> HDFS {{DelegationTokenIdentifier.toString()}} adds some diagnostics info, owner, sequence
number. But its superclass,  {{AbstractDelegationTokenIdentifier}} contains a lot more information,
including token issue and expiry times.
> Because  {{DelegationTokenIdentifier.toString()}} doesn't include this data,
> information that is potentially useful for kerberos diagnostics is lost.
