Hello Dimitris Tsirogiannis,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).
Change subject: IMPALA-4260: Alter table add column drops all the column stats

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.
