hbase coprocessor availability issue in 0.90.4
I am currently using habse 0.90.4.
I want to implement Coprocessors. I know that coprocessors were part of
0.92 and in hbase book, it is clearly mention that Coprocessors are
currently on TRUNK.
Is there any way to implement coprocessors in 0.90.4 or will it be
available in next release?

Best Regards,

Hi,
The current release candidate for 0.92 has all the coprocessor goodness included. Try it if you like and let us know if it worked out for you.
Cheers,
Lars

Arsalan,
> Can you provide example of coprocessors using 0.92
The unit tests provide some limited examples: http://svn.apache.org/viewvc/hbase/branches/0.92/src/test/java/org/apache/hadoop/hbase/coprocessor/
A complete example implementation is the AccessController in 0.92: http://svn.apache.org/viewvc/hbase/branches/0.92/security/src/main/java/org/apache/hadoop/hbase/security/access/
This Coprocessor implements the MasterObserver and RegionObserver interfaces. It also extends RPC with an Endpoint (a custom RPC protocol), as AccessControllerProtocol.

I need to recover some content on Coprocessor development posted to a blog a while back. It will appear on the HBase wiki when I can get it back. In the meantime, there is:

@Harsh: How can we implement coprocessors in hbase? Can you provide example
of coprocessors using 0.92 or any other informative link to use?

Hi Andy,
Thanks for the pointer to the 0.20.205.0 release.
We are constrained to use Scientific Linux for our cluster and although SciLin is close to Red Hat from experience CDH does not just drop into place. We've got used to managing Hadoop/HBase for our cluster. So I'd like to avoid CDH3 for now. We will try building 1.0 for ourselves first. Plan B will be the 0.20.205 release you pointed out.
Just to clarify: browsing the SVN repo it looks like hadoop/common/branches/branch-1.0 and hadoop/common/tags/release-1.0.0-rc2 are identical. Is that correct?

Royston,
Hadoop 1.0 was/is also known as the 0.20.20x branch. It's confusing, I apologize.
The current release of that branch is 0.20.205: http://hadoop.apache.org/common/releases.html#17+Oct%2C+2011%3A+release+0.20.205.0+available .
A "1.0" release from this lineage should be happening soon. The corresponding branch in Apache SVN is "branch-1.0".
Until a release happens, CDH3 is your best option for HBase.

Hi Andy,
Thanks for your reply. I had not realised there is a Hadoop 1.0. Can you tell me if there is a release for it or do I have to build my own from the source?

This is not recommended or supported, due to lack of append support in HDFS in that release. Consider Hadoop 1.0 or CDH3.

Hi,
Does hbase-0.92.0-candidate-0 run with hadoop 0.20.2?

Arsalan,
For the Coprocessor feature, you will need to upgrade to the 0.92 release or later.
