> ----------------------------------------------------
>
> Key: APEXCORE-274
> URL: https://issues.apache.org/jira/browse/APEXCORE-274
> Project: Apache Apex Core
> Issue Type: Bug
> Reporter: Isha Arkatkar
> Assignee: Isha Arkatkar
> Fix For: 3.3.0, 3.2.1
>
>
> Physical plan does not have PMapping added for unifiers. Thus, removeTerminatedPartition fails with Null pointer exception. Need to add null check.
> Also, add unit test to cover this scenario.
