                 URL: https://issues.apache.org/jira/browse/HIVE-2617
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Aniket Mokashi


Insert Overwrite table db.tname fails if partition already exists.
For example-
insert overwrite table db.tname PARTITION(part='p') select .. from t2 where 
part='p'; fails if partition 'p' already exists. Workaround is - use db; and 
the fire the command.
>From the source code-
alterPartition(tbl.getTableName(), new Partition(tbl, tpart)); takes String 
tablename as argument and loses db information. Table table = 
newTable(tablename) is called to retrieve table from name. But, it relies on 
currentDatabase value (hence the workaround).
