In Sqlline(Drill), "show tables" on a Hive schema is taking nearly 15mins to 20mins. The schema has nearly ~8000 tables.
Whereas the same in beeline(Hive) is throwing the result in a split second(~ 0.2 secs).
I tested the same in my test cluster by creating 6000 tables(empty!) in Hive and then doing "show tables" in Drill. It took more than 2 mins(~140 secs).
