while using hbase with nutch I am getting following error Mon Jun 23 23:46:24 PKT 2014, org.apache.hadoop.hbase.client.ScannerCallable@7de8edf7, org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to serverone/10.11.21.31:60020 after attempts=1

One problem " ERROR store.HBaseStore - Failed setting up proxy interface " is because your hadoop daemons are not running. While the second " ERROR store.HBaseStore - [Ljava.lang.StackTraceElemen" is because of execption handling problem. So it will be solved when all daemons will work correctly.
