nimbus moves workers to other supervisor/node
Hi All,
We observe that storm (nimbus) often moves workers to other
supervisors/nodes.
It' happens when the storm cluster is in good shape. We suspect it's
related to the heartbeats delays from supervisors to nimbus. Can be ? How
can we check,prove/disprove it?
I think it's better to avoid this since it's expensive operation ..
Thank you in advance,
Vladi

Hi,
I had faced the same problem.. In my case, the workers were not able to
send heartbeats because of long pauses due to garbage collection.
I configured storm workers to use a concurrent mark sweep GC and now it
works fine
Hope this helps
