Hi everybody,

I want to upgrade my HBase cluster (currently running 0.90.2) to 0.94.

Is it possible to upgrade right away or do I need to install 0.92 first ?

If anyone already did this kind of upgrade, do you have some tips and key
notes ?

Thanks,

Amit.

Are you going to use rolling upgrade ?

Cheers

I was thinking of a shutdown & restart.

If anyone did it, I'd be happy to get some pointers of what I should (and
shouldn't) do.

By the way, I'm currently running HBase with hadoop 0.20.3 - should it
affect my upgrade plans in any way ?

Thanks.

From 0.92.2 to 0.94, you can�t use rolling upgrade,because the wire
protocol changed in these versions.
So, yo have to shutdown the cluster, install the new version, update the
HBase classpath and start the cluster with
the new version
