Hi,
I would like to connect to both a 0.94 hbase cluster and a 1.2.2 hbase cluster
from the same JVM
I think that 0.94 client code is not compatible with 1.2.2
do you think it is possible ?
Thank you

I would say no; 0.94 is not wire compatible with 1.2.2 because the former
uses Hadoop IPC and the latter uses protocol buffers. Sorry, Enrico.

Thank you Dima for your quick answer.
Do you think that it would be possible to create a shaded version of the 0.94
client (with all the dependencies) and let it live inside the same JVM of a
pure 1.2.2 client ?
My real need is to copy data from a 0.94 cluster to a new 1.2.2 installation,
but
Sadly, there is no "easy" way to do it (blame filesystem changes and the
rpc differences, among other things).
A while back, someone posted about how he was able to do a snapshot export
between 0.94 and 0.98 [1] but this is not officially supported. Perhaps
someone else has ideas?

Can you take a look at the replication bridge [0] Jeffrey wrote ?
It used both client library versions through JarJar [1] to avoid name
collision.
