Junkai Xue created HELIX-637:
--------------------------------
Summary: StateModelDefinition is not updated when it changed
Key: HELIX-637
URL: https://issues.apache.org/jira/browse/HELIX-637
Project: Apache Helix
Issue Type: Bug
Components: helix-core
Affects Versions: 0.6.4
Reporter: Junkai Xue
Assignee: Junkai Xue
Fix For: 0.6.x
Currently, if StateModelDefinition already exists in the Znode, even it has
already been changed, Helix will not populate the latest version.
It is because in the StateModelDefinition write into ZK function, it only does
create operation instead of update.
Fix: 1. Check whether there already exists StateModelDefition.
2. Compare if it is different or not.
