-----------------------------------------------
bq. > isJobStarted and isTaskStarted should be in JTClient instead of
MRCluster.
bq. What it makes difference if I moved these methods in JTClient ? Can you
please elobrate more?
from the design perspective {{MRCluster}} is a cluster proxy which provides
access to daemon but not there respective APIs. Conceptually, MRCluster
shouldn't be aware about job or task specific states. Neither, it is logical to
expect these information from a cluster proxy class.
