I may not be able to work on this in the near future. I was planning to knock
out some of the other JIRAs I have on my plate. But if this is not super-urgent
it would be a good starter JIRA for [~bharos92] who is looking to contribute.
Feel free to take it up [~ashutoshc] if you would like to take it up as well.

> Project: Hive
> Issue Type: Bug
> Reporter: Carter Shanklin
> Priority: Major

> Given the other ways schematool is used, the most obvious guess I would have
> for initializing the Hive schema is:
> {code}
> schematool -metaDbType mysql -dbType hive -initSchema
> {code}
> Unfortunately that fails with this NPE:
> {code}
> Exception in thread "main" java.lang.NullPointerException

> Two additional arguments are needed:
> -url jdbc:hive2://localhost:10000/default -driver
> org.apache.hive.jdbc.HiveDriver
> If the user does not supply these for dbType hive, schematool should detect
> and error out appropriately, plus give an example of what it's looking for.
