      Description

      Symptom:
      >>initialize trafodion;

          • ERROR[8448] Unable to access Hbase interface. Call to ExpHbaseInterface::rowExists returned error HBASE_ACCESS_ERROR(-705). Cause:
            java.io.IOException: Problem with calling coprocessor, no regions returned result
            org.apache.hadoop.hbase.client.transactional.TransactionalTable.checkAndPut(TransactionalTable.java:451)
            org.apache.hadoop.hbase.client.transactional.RMInterface.checkAndPut(RMInterface.java:281)
            org.trafodion.sql.HBaseAccess.HTableClient.putRow(HTableClient.java:889)
            org.trafodion.sql.HBaseAccess.HTableClient.checkAndInsertRow(HTableClient.java:965)

      hbase shell list shows trafodion objects stop at TRAFODION.MD.VIEWS_USAGE and

      TRAFODION.REPOS.METRIC_QUERY_AGGR_TABLE
      TRAFODION.REPOS.METRIC_QUERY_TABLE
      TRAFODION.REPOS.METRIC_SESSION_TABLE
      TRAFODION.REPOS.METRIC_TEXT_TABLE

      Cause:
      Presence of both a RegionServer Default Group AND RegionServer Group 1
      After install, only the RegionServer Default Group had coprocessor information
      org.apache.hadoop.hbase.coprocessor.transactional.TrxRegionObserver,org.apache.hadoop.hbase.coprocessor.transactional.TrxRegionEndpoint,org.apache.hadoop.hbase.coprocessor.AggregateImplementation

      Solution:
      remove region server using wrong group and add using Default Group
      remove RegionServer Group 1

      Prevention:

      The install scanner should verify all regionservers used by trafodion use the same RegionServer Default Group

      After the trafodion mods are run, perhaps the regionserver xml files could be checked.
