Description

Currently, NFS updates the user/group id cache every 15 minutes by default. However, it's preferred to have an option to refresh the list without restarting NFS gateway. This is especially useful in the environment where user accounts change frequently.
Otherwise, the user can't access the HDFS mount immediately after they are creating in LDAP or etc.
