Kuhu Shukla created TEZ-3723:
--------------------------------
Summary: TezIndexRecord#hasData() returns true for empty index
record in the Unordered case
Key: TEZ-3723
URL: https://issues.apache.org/jira/browse/TEZ-3723
Project: Apache Tez
Issue Type: Bug
Reporter: Kuhu Shukla
Assignee: Kuhu Shukla
In the case of Unordered writer, use of {{hasData()}} returns true for empty
partitions since the rawlength is zero (as writer skips writing them out
altogether) and the check in hasData will fail as {{rawlength == header.length
+2}} fails.
This currently works for the ordered case(and the method is used here unlike in
unordered writer) but after TEZ-3605, it will fail for both scenarios. Even if
we don't use the method, the logic should be fixed.
