> Some streaming jobs use local mode job runs that do not start tasks trackers.
> In these cases, the jvm context is not setup and hence local mode execution
> causes the code to crash.
> Fix is to not not use ResourceCalculatorPlugin in such cases or make the
> local job run creating dummy jvm contexts. Choosing the first option because
> thats the current implicit behavior in Linux. The ProcfsBasedProcessTree
> (used inside the LinuxResourceCalculatorPlugin) does no real work when the
> process pid is not setup correctly. This is what happens when local job mode
> runs.
