overhead of running analyze on Hive tables.

overhead of running analyze on Hive tables.

This may be a direct question it would be great if you can give me some insights on "Running analyze". updating stats always helps. but

what'll be the burden cost of running analyze at the cluster level.

how can we measure cost for running analyze on bigger tables(around TBs).

please share me some details or docs if available about running stats on the hive tables.
