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:
https://issues.apache.org/jira/browse/HDFS-9085?focusedCommentId=14791503&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14791503
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.

> 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.
