INLINE COMMENTS
ql/src/test/queries/clientpositive/alias_casted_column.q:1 you forgot to add
the output file for this
ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java:1185 do you
want to add a indirection ?
something like:
isOpPreserveInputName() -- which can call isOpCast (isOpCast can be private).
and the caller (SemanticAnalyzer can call isOpPreserveName). If in future
there
is another function with this requirement, it would be easy.
