DTM UnknownTransaction exception messages floods the system and greatly impact the Trafodion installation

This problem was experienced on the bronto[05-08] system, with a CDH 5.3 Hadoop installation, Trafodion R1.1. 032915 build.

Analysis of the trafodion.dtm.log on bronto05 demonstrate that we have a window of opportunity for an UnknownTransactionException to be received for abort and commit TransactionManager requests.
