> 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.
