Thanks. I tried to call some MR using the 0.94.2 jar on a 0.94.0
cluster and it's working fine.
To install it on the cluster I have done a full install on the nodes
and re-started them one by one. Seems it worked fine.
The only issue was with the master since I don't have a secondary
master. I was on 0.94.0 so HBASE-6710 had no impact to me.
