> If we don't assign MANAGEDLOCATION in a "create database" query, the
> MANAGEDLOCATION will be NULL so HMS doesn't create the directory. In this
> case, a CTAS query immediately after the CREATE DATABASE query might fail in
> MOVE task due to "destination's parent does not exist". I can use the
> following script to reproduce this issue:
> {code:java}
> set hive.support.concurrency=true;
> set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
> create database testdb location '/tmp/testdb.db';
> create table testdb.test as select 1;
> {code}
> If the staging directory is under the MANAGEDLOCATION directory, the CTAS
> query is fine as the MANAGEDLOCATION directory is created while creating the
> staging directory. Since we set LOCATION to a default directory when LOCATION
> is not assigned in the CREATE DATABASE query, I believe it's worth to set
> MANAGEDLOCATION to a default directory, too.
