Hey gang,

Now that branch-23 has PB and (almost) HA checked in, it would be good
to get these out into the wild so more people can start kicking the
tires.

How about we cut a 23.3 release soon from branch-23? Or perhaps
re-branch 23.2 if that's easier.

Thanks,
Eli

    Giving release soon would be good idea. I have seen many people waiting for the initiaal HA release. So, that we will get the feedback soon from the users for more stabilization.
    Also can start Automatic fail-over with full focus.

    Regards,
    Uma

    +1, I agree we should do 23.3 ASAP with HA. There are a couple JIRAs
    worth resolving before we do the release, but some time in the next
    couple weeks we should be ready to cut an RC.

    I apologize for asking a dumb question. I know what HA is, but what does PB stand for?

    Thanks,
    Dave

    Dave,

    As Uma expanded it, its Protocol Buffers
    (http://code.google.com/p/protobuf/), we now use it for performing all
    of Hadoop's internal RPCs. One good reason for the change, was to
    introduce (and to simplify) IPC wire compatibility so that clients can
    talk to different major versions of servers (which isn't possible
    today).

    You can find more information in Sanjay's document here:
    https://issues.apache.org/jira/browse/HADOOP-7347 (and all its
    associated JIRAs)

    I merged HA into 0.23.

    I agree we should cut a release from 0.23. There are couple of jiras and
    work that is remaining that I would like to see get in, before cutting a
    release. Some are lingering things from protobuf changes. Also there is
    some work going on to use the same common code for HDFS and MRV2 for
    protobuf engine etc. This work will affect both the APIs and on the wire
    serialization. We should that get in, to avoid making this release
    incompatible with the future or spend a lot of effort trying to make them
    compatible.

    This work should be wrapped up in a few weeks.

    Regards,
    Suresh

    Do all these changes have jiras with target version 0.23.3?

    Hey Suresh,

    How's this working going? What jiras track it?
