-------------------------------------------
Here are some examples of what is stored in LocalState
{code}
{local-assignments={1024
#backtype.storm.daemon.supervisor.LocalAssignment{:storm-id
"topologytest-0e9ff9c4-2e3a-403d-b334-0ce687bcee1a-1-0", :executors ([8 8] [12

{worker-heartbeat={:time-secs 1, :storm-id

> LocalState should not use java serialization

> Key: STORM-765
> URL: https://issues.apache.org/jira/browse/STORM-765
> Project: Apache Storm
> Issue Type: New Feature
> Reporter: Robert Joseph Evans
>
> If we want to do rolling upgrades we need to move away from java
> serialization, as it does not provide a good rolling upgrade path. For
> zookeeper we have been using thrift and I think we want to continue down that
> path here too.
