[jira] [Commented] (HADOOP-13363) Upgrade protobuf from 2.5.0 to something newer

["Andrew Wang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-13363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15958057#comment-15958057 ] 

Andrew Wang commented on HADOOP-13363:
--------------------------------------

[~kihwal] thanks for bringing this up. I believe this scenario will be covered by our existing fsimage upgrade tests, which run on checked-in fsimages.

Hi [~ozawa], what's the schedule for getting this committed? I'd like alpha3 to be our last alpha, and this is not a change I want to sneak in between alpha3 and beta1. The current planned date for alpha3 is May 15th.

Also to be very explicit, I consider shading PB everywhere to be a prerequisite for upgrading to PB3.

> Standard protobuf 2.5.0 does not work properly on many platforms.  (See, for example, https://gist.github.com/BennettSmith/7111094 ).  In order for us to avoid crazy work arounds in the build environment and the fact that 2.5.0 is starting to slowly disappear as a standard install-able package for even Linux/x86, we need to either upgrade or self bundle or something else.
