             Summary: Dropping hive database/table which was created explicitly in default database location, deletes all databases data from default database location
                 Key: HIVE-16950
                 URL: https://issues.apache.org/jira/browse/HIVE-16950
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 1.2.1
            Reporter: Rahul Kalgunde
            Priority: Minor


When database/table is created explicitly pointing to the default location, dropping the database/table deletes all the data associated with the all databases/tables.

Steps to replicate: 
in below e.g. dropping table test_db2 also deletes data of test_db1 where as metastore still contains test_db1

hive> create database test_db1;
OK
Time taken: 4.858 seconds

hive> describe database test_db1;
OK
test_db1                hdfs://sandbox.hortonworks.com:8020/apps/hive/warehouse/test_db1.db     root    USER
Time taken: 0.599 seconds, Fetched: 1 row(s)

hive> create database test_db2 location '/apps/hive/warehouse' ;
OK
Time taken: 1.457 seconds

hive> describe database test_db2;
OK
test_db2                hdfs://sandbox.hortonworks.com:8020/apps/hive/warehouse root    USER
Time taken: 0.582 seconds, Fetched: 1 row(s)

hive> drop database test_db2;
OK
Time taken: 1.317 seconds

hive> dfs -ls /apps/hive/warehouse;
ls: `/apps/hive/warehouse': No such file or directory
Command failed with exit code = 1
Query returned non-zero code: 1, cause: null

hive> describe database test_db1;
OK
test_db1                hdfs://sandbox.hortonworks.com:8020/apps/hive/warehouse/test_db1.db     root    USER
Time taken: 0.629 seconds, Fetched: 1 row(s)
