Shi Lu updated HELIX-25:
------------------------
Assignee: dafu (was: Shi Lu)
Summary: setConfig should check if instance exist or not when setting PARTICIPANT config
(was: enableInstance should check if instance exist or not)
We need to make sure that setConfig does nothing when setting a participant config which is
not added into cluster yet. As some code in helix use the childnames of /CONFIGS/PARTICIPANT
to get the list of instances in the cluster
