[jira] [Created] (PIG-5307) NPE in TezOperDependencyParallelismEstimator

Rohini Palaniswamy created PIG-5307:
---------------------------------------

             Summary: NPE in TezOperDependencyParallelismEstimator
                 Key: PIG-5307
                 URL: https://issues.apache.org/jira/browse/PIG-5307
             Project: Pig
          Issue Type: Bug
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
            Priority: Minor
             Fix For: 0.18.0


In case of the constant being null, NPE is thrown. This was encountered by a user who was generating the field name based on a condition which expanded to NULL when condition was not met. For eg:
{code}
x = FILTER x BY (chararray) NULL == 'fieldvalue';
{code}
