---------------------------------

             Summary: non-string values in supervisor.scheduler.meta cause crash
                 Key: STORM-2429
                 URL: https://issues.apache.org/jira/browse/STORM-2429
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core
    Affects Versions: 1.0.3
            Reporter: David Judd
            Priority: Minor


The type of values in supervisor.scheduler.meta is not validated, but if one is not a string, supervisors crash during Thrift serialization with:

java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.String

I will attach a PR with a simple fix
