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. 2012/10/17, Stack <[email protected]>: > On Tue, Oct 16, 2012 at 7:00 AM, Jean-Marc Spaggiari > <[email protected]> wrote: >> Hi St.Atck, >> >> Is the foll out upgrade process documented anywhere?
