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.
