> 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
> at
> org.apache.hadoop.hive.metastore.tools.HiveSchemaHelper.getDbCommandParser(HiveSchemaHelper.java:570)

> 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.
