(Get the code!)
Chirag provided a DDL/DML script to reproduce the problem. I tried this script on a workstation with the latest (032615) R1.1.0 build. The script ran without any "performScan" errors.
It was suggested that the Trafodion installed version be upgraded to the latest build and tried again on the test cluster.
We have seen "performScan" errors when the various components are not all up to date and in-sync.
There is also one remaining "performScan" problem being addressed in the TrxRegionEndpoint coprocessor.
This problem can be confirmed to be the same issue by setting the HBase tracing to TRACE.
We'll wait for the Trafodion instance upgrade and see if the problem can be reproduced.
