Effects of setting fetch_nonlocal_groups=false

Effects of setting fetch_nonlocal_groups=false

Expert Contributor

We were having very long restart times. Set for the hadoop accounts as described in

This didn't seem to help a lot until we also set fetch_nonlocal_groups=false, using the following command:

/var/lib/ambari-server/resources/scripts/ set Sandbox cluster-env fetch_nonlocal_groups false

My question is this safe/recommended to set this option on in production? Will it disable group lookups for all users including "real" (users and applications) as well as the system accounts?
