Yo have to check in the docs version, in the section 2.3 Hadoop of the
HBase book, which is the
compatible version:
http://hbase.apache.org/book/book.html#hadoop
Regards.

Hi all,
I just upgraded from HBase 0.90.2 to 0.94 (running on hadoop 0.20.3).
It seems like the cluster is up and running.
I tried running an old MR job that writes into HBase, and after Map is
complete (map 100%) and before Reduce begins (reduce 0%) - I got the
following Exception:

I saw something about the dependencies in HBASE-5497 and 5460 - but I
understand that those were fixed in 0.94...
Any ideas ?
Thanks,
Amit.
