There's a DNS mismatch: devperf-sn10,60020,1307732557915 devperf-sn10.pcs.hds.com,60020,1307732557915
And 0.90 has a big regression with that (0.92 already has the fixes, but it's not released yet). Make sure your nodes all resolve the same hostnames per http://hbase.apache.org/book.html#dns BTW the clue comes from those kinda lines: 2011-06-10 12:03:50,975 INFO org.apache.hadoop.hbase.zookeeper.RegionServerTracker: No HServerInfo found for devperf-sn10.pcs.hds.com,60020,1307732557915 J-D On Fri, Jun 10, 2011 at 9:26 PM, Sujee Maniyam <[email protected]> wrote: > looks like this RS has the ROOT region.
