[jira] [Updated] (PIG-4503) [Pig on Tez] NPE in UnionOptimizer with multiple levels of union

     [ https://issues.apache.org/jira/browse/PIG-4503?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rohini Palaniswamy updated PIG-4503:
------------------------------------
    Description: 
   When there are multiple levels of union, with the last union having both store and an output (group by,join, etc) following it then there is a NPE in 

{code}
if (succ.isVertexGroup()
                        && succ.getVertexGroupInfo().getOutput()
                                .equals(succOp.getOperatorKey().toString())) {
                    succOpVertexGroup = succ;
                    break;
                }
{code}

It should check for getOutput() != null as it now has a store vertexgroup

   When there are multiple levels of union, with the last one ending in store there is a NPE in 

{code}
if (succ.isVertexGroup()
                        && succ.getVertexGroupInfo().getOutput()
                                .equals(succOp.getOperatorKey().toString())) {
                    succOpVertexGroup = succ;
                    break;
                }
{code}

It should check for (getStore() != null || getOutput() equals succOpKey)
