> Discuss proper values for sending heartbeat interval, checking timeout
interval
Currently, RemoteInterpreterProcess sends heartbeat every 1 sec, and also
checks timeout every 1 sec.
Please let me know if you think it is too often.
> Discuss how to let users know when remote interpreter is timed out
Currently, Zeppelin can notice users via showing
InterpreterProcessHeartbeatFailedException when executing any client-related
works.
Please share your ideas to improve this feature.
> Discuss possible way to restore remote interpreter back to normal
At first, I thought it would be good to force-kill and re-run remote
interpreter process automatically when timed out. But remote interpreter
process is stateful so users may not want it.
#480 could be a good way to let users restart interpreter by hand if
problem occurs.
Please share your ideas to improve this feature.
