Does it seem reasonable that I could get Stargate 20.6 to work with Hbase
20.2? I need some of the improvements made in 20.6, but would rather not
have to upgrade my entire cluster if I don't have to.

It's strongly recommended that you upgrade to HBase 0.20.6 (at least) if not HBase 0.90.0.  There are several critical bug fixes in the releases between 0.20.2 and 0.20.6 besides stargate.

Thanks, decided to bite the bullet and just update to 0.90.0.

I couldn't find any specific migration instructions for 0.90.0 other than
http://wiki.apache.org/hadoop/Hbase/HowToMigrate.

Is this the case?

The basic steps are the same, but to go from 0.20 to 0.90 there is no actual "migrate" step.  On the HBase side, all that is required is shutting down the old version and coming back up with the new version.  You need to handle the Hadoop upgrade as well as laid out on that wiki page.

You may want to backup your hbase directory on HDFS to be safe.  Once you upgrade to 0.90 there is no easy way to go back unless you have a backup.

Hey Mike: What Jon says.  You might want to check out yesterday's
announcment.  It has a paragraph on migration:

Thanks guys, everything appeared to go smoothly, but i'm getting stuck on

Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch.
(client = 42, server = 41)

And thus the master won't start up. I upgraded Hadoop to 0.20.2. Anything to
try aside from that? I googled around and only saw this error come up in the
context of 0.90.0 rc2.

Cheers,
Mike

I ended up copying hadoop-core from hadoop/20.2 and that seemed to fix it
(although it's still not up and running yet, debugging a few other issues).

Yes that would work.

But you should look at moving to 0.90 when reasonable to do so.

Subject: stargate 20.6 with hbase 20.2

Does it seem reasonable that I could get Stargate 20.6 to work with Hbase
20.2? I need some of the improvements made in 20.6, but would rather not
have to upgrade my entire cluster if I don't have to.
