Re: About 2.7.4 Release

[Konstantin Shvachko]

Hey guys.

An update on 2.7.4 progress.
We are down to 4 blockers. There is some work remaining on those.
https://issues.apache.org/jira/browse/HDFS-11896?filter=12340814
Would be good if people could follow up on review comments.

I looked through nightly Jenkins build results for 2.7.4 both on Apache
Jenkins and internal.
Some test fail intermittently, but there no consistent failures. I filed
HDFS-11985 to track some of them.
https://issues.apache.org/jira/browse/HDFS-11985
I do not currently consider these failures as blockers. LMK if some of them
are.

We started internal testing of branch-2.7 on one of our smallish (100+
nodes) test clusters.
Will update on the results.

There is a plan to enable BigTop for 2.7.4 testing.

Akira, Brahma thank you for setting up a wiki page for 2.7.4 release.
Thank you everybody for contributing to this effort.

Regards,
--Konstantin

 Latest update on the links and filters. Here is the correct link for the

 Had to do some Jira debugging. Sorry for confusion.
