Hi, I am using the latest HBase trunk on top of hadoop 0.20.0. I have a MR job that digests records and stores them in a table in HBase.
Hadoop/HBase/ZooKeeper are deployed on a cluster of 5 machines (Linux, 64bits, 16Gb or RAM, 2x1Tb of disk). After some time, the MR job fails exceptions similar to: "org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact region server Some server for region ...." This looks like the problem described in HBASE-1603 except the split of the region that the job fails to access occurs very close to the time of the failure. HBASE-1615 is applied to the version of HBase trunk this problem occurs on. Anyone else experiencing that? Mathias.
