Comment the finished compiled work debug message, it sucks by writing too often
remove unused code
Add more debug messages to MapReduceHelperThread
Find the system procedure LoadMultipartitionedTable not working properly; Add more debug messages here
Revert back of the feature to start MR helper thread when needed, still need to debug this feature
Figure out the system procedure LoadMultipartitionTable can not load data to database properly
Comment this test case for the reason that Forked Java VM exited abnormally
Not sure why there should be this change
run mr test cases
