Subject Re: how to keep storm running when console ends
Date Fri, 04 Aug 2017 15:14:47 GMT
I don't know much about storm but I do think you are making a good point. 
If there is no good reason for this current fashion, I think we probably should improve the
scripts.

 thanks for all the responses. screen and nohup seem easy to adopt. 
I guess for something intended to run on large clusters I'm surprised at the default behavior
of storm. It seems quite the opposite of what I would've guessed. 
I also have a Heron instance running in similar fashion and it's default behavior is to keep
running which seems more what I expected.

Try adding nohup at the beginning of each of those commands.  Nohup prevents a process from
terminating when it's parent shell is closed.
nohup /opt/storm/apache*/bin/ storm nimbus &

Hi,
Storm docs recommend to use daemontools or monit which provides error recovery and etc.. 
I use linux "nohup" or "screen" command for simplicity.

 this seems silly but I have not figured out how to keep nimbus, supervisor running after
console session ends. zookeeper survives but supervisor and nimbus shut down when the console
session ends.
I have storm 1.0.2 installed under /opt/storm and starting up as:/opt/storm/apache*/bin/storm
nimbus&/opt/storm/apache*/bin/storm supervisor&
/opt/storm/apache*/bin/storm ui&
/opt/storm/apache*/bin/storm drpc&

I know I can add a while loop to keep the console active but there has to be a better way
