Subject [jira] [Updated] (HELIX-144) Need to validate StateModelDefinition when adding new StateModelDefinition to Cluster
Date Wed, 24 Jul 2013 04:12:48 GMT

     [ https://issues.apache.org/jira/browse/HELIX-144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

dafu updated HELIX-144:
-----------------------

    Description: 
we see that when DROPPED state is not in the StateModelDefinition, partition will fail to
be dropped. this causes problem when we are using auto_rebalance mode, because we are dropping
mappings and assign new mappings to nodes. things need to verify:
1) state transitions are all valid, no self loop/loop
2) constraints are valid
3) drop state included
