Subject show tables taking long time on hive plugin

Drill 1.6.0

Hive Default database has 1400 tables.

I see significant slow down in "show tables" when Hive database is bigger
than 500 tables.
It takes 3 minutes to get the resultset.
There is no obvious logs on drillbit or zookeeper to help diagnose the

Beeline is snappy, returns 1400 tables in a second or so.

Why Drill "show tables" on Hive plugin takes this long?
