Zheng Shao updated HIVE-437:
----------------------------
Attachment: HIVE-437.2.code-only.patch
Talked with the team offline and make some changes:
1. We will now output an error if an identifier in the expression can be both a
table alias and a column.
2. The Expression GraphWalker's process will return NULL for a table name.
Originally we were returning a String for table name, and exprNodeDesc for
others, which is not good. I didn't change the PartitionPruner in the same
direction, because we are going to refactor that code completely pretty soon.
> Allow both table.col and col.field in the grammar
