Bug #6815
closedAvailability of schedulers is checked badly
0%
Description
At the moment controllers check for schedulers availability by checking that command:
ps -aux | grep -F SCHEDULER_BINARY_NAME -c
output more than 2 lines. This is buggy and one of solutions suggested here should be used instead.

I used 'ps -aux | grep [n]ative-scheduler' soulution to support running scheduler from PyCharm. Approach with pgrep matches only process name which is "Python3.4" currently and it cannot be changed in case of PyCharm. And approach "pgrep -f" still matches itself as original one.
Fixed in branch "scheduler-controller-check" and ready for merge to "master".

It is of course better than it was before (at least schedulers shouldn't be disconnected unexpectedly) but nevertheless it is still bad since, for instance, if I open file "*native-scheduler*" in some editor the controller will think that Native Scheduler is operating. Since the latter is not so awful as suddenly disconnected schedulers I would like to implement proper checks in #6541.
