Hi, all
I have enabled hive authorization in my testing cluster. I use the user
hive to create database hivedb and grant create privilege on hivedb to user
root.
But I come across the following problem that root can not create table in
hivedb even it has the create privilege.
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.DDLTask.

It is obviously that the hivedb.db directory in HDFS are not allowed to be
written by other user. So how does hive authorization work under the HDFS
permissions?
PS. if I create a table by user hive and grant update privilege to user
root. The same ERROR will come across if I load data into the table by root.
Look forward to your reply!
Thanks
