Hi Austin

In hive currently you can have permissions only on the hdfs layer not on the metastore. The
current hive metastore don't have multiuser permission support. Any user will be able to drop
the metadata information now.

Subject: Multiuser setup on Hive


I had been trying to set up a multi user environment for hive.
I have set up the hive metastore db in MySQL and hive works.

Consider this scenario:

user1 has created a database data1
user2 has created a database data2

Now user2 logs into hive and he is able to see and delete database data2

How do I prevent this?
