-------------------------------------
Hi Juan,
The issue got reproduced in my machine with hive 0.12 version. I am using
Derby for metastore in server mode. Earlier when i drop the table i recieved
different exception.
drop table Test;
The error i got is
Caused by: MetaException(message:java.lang.RuntimeException: commitTransaction
was called but openTransactionCalls = 0. This probably indicates that there are
unbalanced calls to openTransaction/commitTransaction)
After applying HIVE-4996 patch, receiving same exception you have reported.
drop table Test;
NestedThrowablesStackTrace:
java.sql.BatchUpdateException: DELETE on table 'TBLS' caused a violation of
foreign key constraint 'TAB_COL_STATS_FK1' for key (19).
But with or without applying patch, drop table test; [ small 't'] works.
There is some issue.
