I checked the webUI, the logs and HBCK all over the process and they are
all reporting well.
Last, integration test is running for the 2 last hours with no issues.

The HBase Team is pleased to announce the immediate release of HBase 0.94.19.
Download it from your favorite Apache mirror [1]. This release has also been
pushed to Apache's maven repository.
All previous 0.92.x and 0.94.x releases can upgraded to 0.94.19 via a rolling
upgrade without downtime,
Getting folks test releases is like pulling teeths, or herding cats, or getting
three kids to agree which song from Frozen is the best :)
All jokes aside, this *is* a problem. With the goal of more frequent releases
release verification needs to be a smooth process.
I do not know how to fix it,
Resending... Looks like first attempt did not go through (still Apache email
issues?).

I'd like to do an RC for 0.94.20 soon. Looks like it'd be a nice and small
release, only 7 fixes so far. 0.94 is maturing. :)
Anything that should get pulled in?
Thanks.

Doing some local testing I noticed that replication does not work with Hadoop
1.0.x or Hadoop 1.1.x when SSR is enabled.
Was banging my head at it for a while and until I realize what the issues was,
then I also came across this: https://issues.apache.org/jira/browse/HDFS-2757
(which J-D fixed).
Looking. Seems like a bug we should fix.

Hi Lars,Andrew,
Could you take a look at HBASE-11096?
Thanks.

But note that such a high level interface will probably not allow access at
level necessary for Phoenix.
You can't eat your cake and keep it. For some performance you deep access to
HBase internals (RegionScanners, for example). At the same time, these *are*
internal.
I suppose to least we can
We've seen similar issues with Filters. Those are good rules to follow.

That would be separate use case, though.
It's easy to say coprocessors are too invasive, but that is what they were
designed for: A way to extend region server and HMaster without requiring
subclassing the main classes and taking over completely.

use case, and that we'll keep the old stuff.
