For a batch job with partitioned step, the PartitionReducer's afterPartitionedStepCompletion gets ROLLBACK on normal completion.

[scottkurz]

Describe the bug

For a batch job with a partitioned step, with a PartitionReducer configured, during normal completion the reducer's afterPartitionedStepCompletion gets passed a PartitionStatus.ROLLBACK value even when a step completes normally.

Steps to Reproduce
Define a partitioned step with a reducer configured, like:

<step id="step1">
	<chunk/>
	<partition>
		<plan partitions="3"/>
		<reducer ref="MyReducer">

and observe the value passed to MyReducer's afterPartitionedStepCompletion(PartitionStatus status) method upon normal completion.

Expected behavior

For a successful execution, the status passed to the reducer in afterPartitionedStepCompletion would be COMMIT, and for a failing execution it would be ROLLBACK
