> 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
