Is it possible to disable column level security at Hive

[#1]

I don't use column security in ranger. but when I apply any operations to a table consisting of 4000 columns, HIVE checks all privileges on the columns for a very long time. On postgres, I see 1 million selects to get information for each grant id

To gain a better understanding of the issue, kindly provide the HS2 jstacks at 30-second intervals until the query completes
