Summary: [Pig on Tez] NPE in UnionOptimizer with multiple levels
of union
Key: PIG-4503
URL: https://issues.apache.org/jira/browse/PIG-4503
Project: Pig
Issue Type: Bug
Affects Versions: 0.14.0
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: 0.15.0
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)
