Hi Devs I discussed this with Lars, thought it would be better to get the opinion of the dev list. It is regarding the 0.94 RC
HBASE-5964 seems to be needed if we want to run with 0.94.0 and hadoop 2.0 (latest). Also the Guava jar related issue HBASE-5955 may also be needed i.e HBASE-5739 patch backport is needed to solve that problem. All this happens if we take the latest hadoop 2.0. A little older version of hadoop 2.0 may not cause this problem. But older version has a filehandler leak in DN side for which Todd has provided fix in hadoop side. Refer to HDFS-3359. We can easily reproduce this problem if we have a multiple column family table and frequent flushes happen and it impacts HBase heavily. So we felt, all these issue needs to go in 0.94.0 release as we claim 0.94 supports 0.23. What do you think? If you feel this is needed then we might need to go with one more RC sinking the current one.
