Hyunsik Choi created TAJO-189:
---------------------------------
Summary: LazyTuple should return NullDatum if a column is null
Key: TAJO-189
URL: https://issues.apache.org/jira/browse/TAJO-189
Project: Tajo
Issue Type: Improvement
Components: physical operator
Reporter: Hyunsik Choi
Priority: Blocker
Fix For: 0.2-incubating
When a query including LIKE expression is executed, LikeEval causes the
following NPE if a operand value is NULL. This is because BinaryEval and
EvalNodes assume that NullDatum comes when it is null. We need to fix it.
