[jira] [Updated] (HELIX-200) helix controller send ERROR->DROPPED
transition infinitely
[ https://issues.apache.org/jira/browse/HELIX-200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
dafu updated HELIX-200:
-----------------------
Description:
when a resource in ERROR state is dropped, helix controller is sending ERROR->DROPPED transition. this causes problems when the participant is in old version where it doesn't implement a default ERROR->DROPPED transition in state model. In this case, participant will go into ERROR state again when receiving an ERROR->DROPPED transition and controller will send ERROR->DROPPED transitions infinitely. This leads too much traffic against zookeeper and may potentially bring down zookeeper
the short term solution is let controller disable ERROR->DROPPED transition for participant with old version.
