Review request for hive, Ashutosh Chauhan, Brock Noland, Szehon Ho, and Xuefu
Zhang.
Bugs: HIVE-9620
https://issues.apache.org/jira/browse/HIVE-9620
Repository: hive-git
Description
-------
The identifier such as column name is stored in lowercase in metastore backend
tables. Hive usually converts these identifiers to lowercase before calling HMS
APIs, but it might not be always true. Other HMS clients like Impala might also
not do that. So we need convert the identifiers in HMS request to lowercase in
HiveMetaStore.java before querying backend tables. Some existing APIs in
HiveMetaStore have already done this conversion but others have not, especially
those APIs for Statistics with StatsRequest. This patch is going to change all
these identifiers passed in StatRequest to lowercase before querying backend
tables.
