Hi Helix team,
I keep seeing this error from HelixStateTransitionHandler when the
state machine is running. It seems a partition's actual state doesn't
match with the state marked in controller message. What are the usual
causes? I'm using helix
0.7.1. Here is my maven pom.xml:
<dependency>
<groupId>org.apache.helix</groupId>
<artifactId>helix-core</artifactId>
<version>0.7.1</version>
</dependency>

Another problem I see is: my ideal state defines a partition has 3
replicas, but the resource's external view shows sometime that a
partition has 4 replicas.
Any hints? Thanks!
