> 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.
