-----------------------------------------
bq. TestAclsEndToEnd failure seems to be caused by this change.
This test failed in [HDFS-11885 Precommit
|https://issues.apache.org/jira/browse/HDFS-11885?focusedCommentId=16040117&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16040117]
also.
I have also created jira HDFS-11944 and will work on that soon.
Last 2 patches were just log messages change and addressing checkstyle issues
that's why I didn't run all the failed tests again.
bq. So please follow wiki's patch naming convention so the branch-2.8 patch
can be applied automatically
I did create the branch-2.8 patch. The last precommit build that ran was for
branch-2.8 {{git revision -- branch-2.8 / e47ec94}}.
I don't fully understand your comment.

> The kms client appears to have no retry logic – at all. It's completely
> decoupled from the ipc retry logic. This has major impacts if the KMS is
> unreachable for any reason, including but not limited to network connection
> issues, timeouts, the +restart during an upgrade+.
> This has some major ramifications:
> # Jobs may fail to submit, although oozie resubmit logic should mask it
> # Non-oozie launchers may experience higher rates if they do not already have
> retry logic.
> # Tasks reading EZ files will fail, probably be masked by framework reattempts
> # EZ file creation fails after creating a 0-length file – client receives
> EDEK in the create response, then fails when decrypting the EDEK
> # Bulk hadoop fs copies, and maybe distcp, will prematurely fail
