IMPALA-4260: Alter table add column drops all the column stats Hive expects types for column stats to be specified as all lower case. For some reason, it doesn't check this when the stats are first written, but it does check when performing an 'alter table'. This causes it to drop stats that Impala wrote because we specify type names in upper case. This patch converts the types that Impala sends to Hive for the column stats to all lower case and adds a regression test. I also filed HIVE-15061 to track the issue from the Hive end.
