Problem Summary: Recommended command to kill hvrscheduler in linux hub
There are 2 ways of killing hvrscheduler
Using hvrscheduler -k
Unix kill command
We recommend using hvrscheduler -k .
Hvrscheduler -k first tries to connect to the old daemon and ask it to suicide. If that fails or tales too long it kills the old scheduler process mentioned in the.pid file, but only after sanity checks, including that the nodenames matches. And it clears up the old .pid file and file with the running node and port info. We recommend this -k option. Using kill -9 will typically work, but is not recommended.
