答复: Exclude certain supervisors?

Yes, we have health check for supervisor. You can put the script which check the connections in the directory  “storm.health.check.dir”, we will check the supervisor’s healthy status by the script at regular intervals. Once we check the supervisor is unhealthy, then we will kill the supervisor and his workers. But you need provide the script.  And the script must output “ERROR” when it find the supervisor war unhealthy. 

 You  can refer to “healthcheck.clj” before you write  the script.

主题: Exclude certain supervisors?

 

Due to some network switch issues, some supervisors are not stable (connection on and off) in my production cluster. I'd like to temporarily exclude those supervisors from connecting to the Storm cluster. Is there a configuration change I can deploy to do so?

 

thx

Daniel

Thanks
