Miklos Gergely commented on HIVE-21034:
---------------------------------------
* "yes" is a command line argument specific to the new task, so it should not
be handled by the MetaStoreSchemaTool, instead the task should obtain it via
setCommandLineArguments
* cmdLine may not be null, so it is not necessary to check it in the catch
block
> Add option to schematool to drop Hive databases

> An option to remove all Hive managed data could be a useful addition to
> {{schematool}}.
> I propose to introduce a new flag {{-dropAllDatabases}} that would *drop all
> databases with CASCADE* to remove all data of managed tables.
