> We update the last.repl.id as a database property. This is done after all the bootstrap
tasks to load the relevant data are done and is the last task to be run. however we are currently
not setting up the DAG correctly for this task. This is getting added as the root task for
now where as it should be the last task to be run in a DAG. This becomes more important after
the inclusion of 
> HIVE-17426 since this will lead to parallel execution and incorrect DAG's will lead to
incorrect results/state of the system.
