-------------------------------
Summary: Vertex.setParallelism should throw an exception for
invalid invocations
Key: TEZ-1699
URL: https://issues.apache.org/jira/browse/TEZ-1699
Project: Apache Tez
Issue Type: Bug
Reporter: Bikas Saha
Priority: Critical
There is a return value of false when setParallelism is not successful. However
that may be ignored and in some cases the invocation is actually incorrect and
its better to throw an exception than return false. Throwing an unchecked
exception can allow doing this compatibly.
