> Hive UT currently uses Derby DB with storage on disk which have some
> practical problems.
> 1. The run-time of Hive unit tests are high as need to operate on the disk
> quite often.
> 2. It can cause conflict if multiple test cases operates on the same table
> name (such as table being created already exist).
> To solve these problems, we shall use an in-memory storage option of Derby DB
> which can be even persisted if the test case demands that.
