improvements in 0.18?

[Tim Sell <tr...@gmail.com>]

I haven't been following the progress as much as I'd like.
We're using hbase 0.2.1 at the moment, and wondering what are the major
improvements in 0.18?
Is the better batching of bulk row updates included? Does that cover when
using map reduce as input/output as well? Has there been any major bug fix /
stability improvements? Just after a quick overview really. I really should
read the jira's more often.

As of right now, thanks to Andrew Purtell, such a thing is possible:
https://issues.apache.org/jira/browse/HBASE-1004

Hadoop 0.19 was just released yesterday, so no longer required to use an RC
or branch checkout of hadoop on hbase trunk.

Oh yes. the changelog..
I'd love to be using hbase 0.19.0 when it's out, but we're being
conservative about hadoop upgrades. I assume it's not possible to compile
hbase 0.19.0 with hadoop 0.18.2?

thanks
~Tim.

Handling of binary keys, an experimental transactional hbase and a bunch 
of critical bug fixes is the short answer.  For more detail, you'll have 
to read the CHANGES.txt (thats that I just did -- smile).

If you can, wait on 0.19.0 hbase, a week or two more I'd say, it'll have 
performance improvements that you'd likely be interested in.

Good on you Tim,
St.Ack
