Hari Sankar Sivarama Subramaniyan commented on HIVE-13615:
----------------------------------------------------------
I think this is a much generic issue which got exposed by the recent parser
changes in HIVE-13290. In general, if we use any of the nonreserved key words
in IdentifiersParser.g as an alias in the statements like below, we will run
into an error:
{code}
FROM src rely
INSERT OVERWRITE TABLE ambiguous SELECT rely.key, rely.value WHERE rely.value <
'val_100';
FROM src key
INSERT OVERWRITE TABLE ambiguous SELECT key.key, key.value WHERE key.value <
'val_100';
FROM src uri
INSERT OVERWRITE TABLE ambiguous SELECT uri.key, uri.value WHERE uri.value <
'val_100';
{code}
> nomore_ambiguous_table_col.q is failing on master
