             Summary: LP Bug: 1379862 - Using HBase 0.98, ustat estimateRowCount() returns 0
                 Key: TRAFODION-690
                 URL: https://issues.apache.org/jira/browse/TRAFODION-690
             Project: Apache Trafodion
          Issue Type: Bug
            Reporter: Barry Fritchman
            Assignee: Barry Fritchman
            Priority: Critical


Update Statistics calls estimateRowCount() for HBase tables rather than executing a count(*) query.  Since moving to HBase 0.98, this function always returns 0, which causes the more expensive count(*) to be used.
