Subject [VOTE] First hbase-2.0.0-alpha-2 Release Candidate is available
Date Wed, 16 Aug 2017 20:43:06 GMT
The first release candidate for HBase 2.0.0-alpha-2 is up at:

  https://dist.apache.org/repos/dist/dev/hbase/hbase-2.0.0-alpha-2RC0/

Maven artifacts are available from a staging directory here:

  https://repository.apache.org/content/repositories/orgapachehbase-1173

All was signed with my key at y 8ACC93D2
<http://pgp.mit.edu/pks/lookup?op=get&search=0x9816C7FC8ACC93D2>

I tagged the RC as 2.0.0-alpha-2RC0
(7149f999786b6fd5a3fc1f7aec1214afb738925e)

hbase-2.0.0-alpha-2 includes all that was in alpha-1 (new assignment
manager, offheap read/write path, in-memory compactions, etc.) plus a
return to branch-1 deploy mode where master carries no regions (branch-2
and master up to this had master carrying system tables), a purge of all
checked-in generated content, updates to all dependencies including a move
to rely on new hbase-thirdparty lib for relocated versions of guava, netty,
and protobuf, etc.

This is a rough cut ('alpha'), not-for-production preview of what
hbase-2.0.0 will look like meant for devs and downstreamers to test drive
and flag us early if we messed up anything ahead of our rolling GAs.

The list of features addressed in 2.0.0 so far can be found here [4]. There
are about 2700+. The list of ~500 fixes in 2.0.0 exclusively can be found
here [3].

I've updated our overview doc. on the state of 2.0.0 [1] but JIRA 2.0.0
label [2] has undergone extensive weeding and presents a fairly good
picture on what is yet to do before we 2.0.0. Check it out.

Please take it for a spin and vote on whether it ok to put out as our first
alpha (bar is low for an 'alpha'). Let the VOTE be open for 72 hours
(Saturday)

Thanks,
St.Ack
