Lefty Leverenz commented on HIVE-17086:
---------------------------------------

Doc note:  The new metric *LlapDaemonLimitFileDescriptorCount* and revised 
meaning of *LlapDaemonMaxFileDescriptorCount* need to be documented in the Hive 
Metrics wiki page, along with other LLAP metrics (see HIVE-16072).

* [Hive Metrics | https://cwiki.apache.org/confluence/display/Hive/Hive+Metrics]

Added a TODOC3.0 label.

> LlapDaemonMaxFileDescriptorCount shows max file descriptors that system will 
> allow. For debugging purpose we could also store the max value that was seen 
> so far to know if we have hit the limit.
