-Re: [DISCUSSION] Sorting out issues for 0.96 for (eventual) release
Stack 2013-01-08, 18:21
Thanks for doing the below Andrew.
I was going to write something to try and rally folks around a 0.96
release. I see loads of work afoot. I am not sure what percentage can be
judged advancing the 0.96RC cause.

As I see it, closing above is all that stands in the way of our branching.
I see different numbers to you if I look on this page  (I see many more
issues than you count).
A while back after survey , here is what we said would be in 0.96 (You
can see the summary when you list 'versions'  in JIRA): "....you will
have to start and stop your cluster bringing it up on 0.96.0. 0.96.0 will
require Hadoop 1.0.0 at least. It will be supported on Hadoop 2.0.0 too.
0.96.0 will be all protobufs all the time; all of its serializations to
zookeeper, to the filesystem, and over rpc will be protobufs. It runs on
jdk7. Metrics will be edited and converted to use Hadoop Metrics2. A
preview of HBase Snapshots and PrefixTreeCompression."
Not mentioned but which will be immediately apparent when 0.96 comes up
will be new UI (smile), Jimmy et als AssignmentManager cleanup, Nicolas and
company's MTTR work -- the list is long.

Yeah, these are significant issues but they are being worked on actively at
I wish it wasn't months. It is not good for the project that so much time
has elapsed between major releases.

High-level, we have had this discussion IMO (). Would you like to do it
Otherwise, I think folks need to bubble up critical issues (or strike them
down) and if any controversial, lets discuss them?

I have a bet with JD on when 0.96 will go out. Going by the timeline you
sling above, it looks like I am going to lose my bet.
Good on you Andrew,
