Warn messages in controller log
Hi Folks,
I'm seeing a set of log lines that are continuously printing in controller
and some errors in between. Do you have an explanation for this?

Re: Warn messages in controller log
Posted by Hunter Lee <na...@gmail.com>.
Hi Dlmuthu,
Could you give us a bit more context? What kind of operations are you doing
and what are the characteristics (config settings) for these workflows?
On a cursory look, it seems that the workflow
"Workflow_of_process_PROCESS_4660666a-6acf-477e-bf97-0671b666dd19-PRE-6a568552-f517-49a1-94c8-c1d3814c3244"'s
WorkflowConfig is missing even though its IdealState exists. A few possible
scenarios are as follows:
1. Some purge operation/delete operation was performed on this particular
workflow; however, the WorkflowConfig was removed successfully, but the
IdealState removal failed. This causes WorkflowRebalancer to print out the
log. This is not very serious and you'll just see a lot of WARN logs. The
fix is to force delete the IdealState that failed to be deleted.
2. Some fundamental assumptions about Helix was broken - (for example,
CLUSTER/CONFIG/RESOURCE folder was removed and re-created) that caused
CallbackHandler to be removed. This will break the Helix Controller and no
workflows will be scheduled. In this case, you have to ensure the cluster
is set up properly and re-start the Controller.
Hope this helps,
Hunter
