> In MapRecordProcessor::getFinalOp() due to external cause(not known), the TezDummyStoreOperator
may have MergeJoin Op as child intermittently. Due to this, the fetchDone remains set to true
for the DummyOp which was set by previous task. Ideally, fetchDone should be reset for each
task. This eventually leads to the join op skip rows from that dummy op resulting in wrong
results.
