Prasanth Jayachandran commented on HIVE-21427:
----------------------------------------------
The syslog input format does not use llap wrappable IF so the logs data will
not use llap io and hence not pollute the cache.

> It will be useful to read syslog generated log files in Hive. Hive generates
> logs in RFC5424 log4j2 layout and stores it as external table in sys.db. This
> includes a SyslogSerde that can parse RFC5424 formatted logs and maps them to
> logs table schema for query processing by hive.
