Prasanth Jayachandran commented on HIVE-19033:
----------------------------------------------
There is no security yet. If this is required to be admin only feature and work
only for secure clusters then I will probably do something like HIVE-18982.
There might be a need for this to be run on unsecure clusters as well hence
leaving it as such. We can always enable
hadoop.security.instrumentation.requires.admin to restrict access to this
endpoint (default is false though)
> Provide an option to purge LLAP IO cache
