Eric Yang resolved AMBARI-102.
------------------------------
Resolution: Fixed
> Heartbeat installedRoleState is returned to as size of 1 when it should be
> empty
> --------------------------------------------------------------------------------
>
> Key: AMBARI-102
> URL: https://issues.apache.org/jira/browse/AMBARI-102
> Project: Ambari
> Issue Type: Bug
> Components: agent
> Affects Versions: 0.1.0
> Environment: Python
> Reporter: Eric Yang
> Assignee: Eric Yang
> Fix For: 0.1.0
>
>
> Instead of sending heartbeat:
> {noformat}
> {
> 'responseId' : 123,
> ..
> 'installedRoleStates' : []
> }
> {noformat}
> In the java side, installedRoleStates is serialized and have object of size
> of 1. This is because Jersey already creates empty object to hold the array
> prior to serialize the empty array. This leads to result of 1 element
> instead of 0.
> The workaround is to not sending empty array as part of heartbeat message,
> hence the heartbeat looks like:
> {noformat}
> {
> 'responseId' : 123,
> ..
> }
> {noformat}
