Re: VOTE: Hadoop Ozone 0.4.0-alpha RC2

2019-05-07 Thread Ajay Kumar 
Thanks for trying out ozone-0.4.0 RC2 release artifacts and for your votes. 
(Re-sending this mail to make minor correction in list of binding +1.)

The vote is PASSED with the following details:
*  3 binding +1, (thanks Arpit, Xiaoyu & Anu) 
*  4 non-binding +1, (thanks Eric, Dinesh, Marton) together with my closing +1 
[*]
*  no -1/0

Thanks again, will publish the release now.

Note: ** We have addressed the issue highlighted by Xiaoyu, renaming 
"hadoop-3.3.0-SNAPSHOT-src-with-hdds" to " hadoop-ozone-0.4.0-alpha-src".
Git hash still remains same. MD5 checksum has been updated for renamed file. 
Release documentation for ozone has been updated to handle this in future 
releases.

Just have one minor question for the expanded source code which points 
to hadoop-3.3.0-SNAPSHOT-src-with-hdds/hadoop-ozone. But in 
hadoop-ozone/pom.xml, we explicitly declare dependency on Hadoop 3.2.0.
I understand we just take the trunk source code(3.3.0-SNAPSHOT up to 
the ozone-0.4 RC) here, should we fix this by giving the git hash of the trunk 
or clarify it to avoid confusion? 
This might be done by just updating the name of the binaries without 
reset the release itself.
