> Java exceptions are not handled in consistent manner in Trafodion. The SQL interface layer in Trafodion is capable of displaying the entire java stack trace to the client application when an exception is raised in java portion of the Trafodion/Hbase/Hdfs stack. However, there are portions of the code in Trafodion where the exceptions are not handled in a consistent manner. This JIRA attempts to fix this.
