Review request for hive and Szehon Ho.
Bugs: HIVE-11464
https://issues.apache.org/jira/browse/HIVE-11464
Repository: hive-git
Description
-------
Fixed missed lineage info when there are multiple inserts in one query
statement. In generating the depedency map, we record the insert target tables
and the corresponding select operators. We used to assume there is just one
final select operator. It could be several, for example, in the multiple
inserts case.
