> Key: TRAFODION-1184
> URL: https://issues.apache.org/jira/browse/TRAFODION-1184
> Project: Apache Trafodion
> Issue Type: Bug
> Components: installer
> Reporter: Chris Tjepkema
> Assignee: Amanda Moran
> Priority: Critical
>
> 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.
