Hi, All
I have 2 questions about supervisor nodes in storm cluster, I have run the https://github.com/intel-hadoop/storm-benchmark for the storm performance test. I found grep and trident topologies will kill supervisor (work) nodes when the test automatically kill the topoplogies after 5 mins. 1. My question is, kill a topology might cause the supervisor node be killed as well? 2. Reading storm's official documentation: "As described in Setting up a Storm cluster, the Nimbus and Supervisor daemons must be run under supervision using a tool like daemontools or monit. So if the Nimbus or Supervisor daemons die, they restart like nothing happened." I have installed the supervisord in cluster (nimbus and worker nodes) [program:storm-nimbus] command=/etc/storm/bin/storm nimbus & user=stuser autostart=true autorestart=true startsecs=10 startretries=999 log_stdout=true log_stderr=true logfile=/var/log/storm/nimbus.out logfile_maxbytes=20MB logfile_backups=10 [program:storm-supervisor] command=/etc/storm/bin/storm supervisor & user=stuser autostart=true autorestart=true startsecs=10 startretries=999 log_stdout=true log_stderr=true logfile=/var/log/storm/supervisor.out logfile_maxbytes=20MB logfile_backups=10 [program:storm-ui] command=/etc/storm/bin/storm ui & user=stuser autostart=true autorestart=true startsecs=10 startretries=999 log_stdout=true log_stderr=true logfile=/var/log/storm/ui.out logfile_maxbytes=20MB logfile_backups=10 However, it just exit all the time, see the log root@DO-mq-dev:/var/log/supervisor# tail supervisord.log 2014-12-17 16:41:24,461 INFO exited: storm-nimbus (exit status 1; not expected) 2014-12-17 16:41:24,556 INFO exited: storm-supervisor (exit status 1; not expected) 2014-12-17 16:41:29,563 INFO spawned: 'storm-supervisor' with pid 349 2014-12-17 16:41:29,565 INFO spawned: 'storm-ui' with pid 350 2014-12-17 16:41:29,566 INFO spawned: 'storm-nimbus' with pid 351 2014-12-17 16:41:29,599 INFO exited: storm-ui (exit status 1; not expected) 2014-12-17 16:41:31,566 WARN received SIGTERM indicating exit request 2014-12-17 16:41:31,566 INFO waiting for storm-supervisor, storm-ui, storm-nimbus to die 2014-12-17 16:41:31,567 INFO stopped: storm-nimbus (terminated by SIGTERM) 2014-12-17 16:41:32,569 INFO stopped: storm-supervisor (terminated by SIGTERM) Any idea what is the problem? thanks Alec
