[Impala] Data Connection refresh timeout

Newly created Data Connection (Impala) over Bridge refresh exceeds a ?30 min timeout. Our database has ~3400 tables and roughly 1/2 pass until the timeout is exceeded. The timeout relates to a `show tables` query.


Can we tweak/extend the aforementioned timeout threshold to allow for a full refresh to complete? Auto-refresh is disabled, updates are triggered manually through the API or UI.
