--------------------------------
Thanks @navis to add the coverage. Sorry, I didn't see the tests already there.
Would it be better to create a class like TableMeta and return a list of
TableMeta instead of list of strings?
To Yongzhi's question: when we have many databases, the performance of the
original getTables could be bad since we are making at least one trip for each
database. Is that right?
> GetTables thrift call is very slow

> The GetTables thrift call takes a long time when the number of table is large.
> With around 5000 tables, the call takes around 80 seconds compared to a "Show
> Tables" query on the same HiveServer2 instance which takes 3-7 seconds.
