Lefty Leverenz commented on HIVE-13954:
---------------------------------------

Doc note:  parquet-logging.properties should be documented for releases 2.1.0 and 1.3.0 in
the Parquet wikidoc, with a cross-reference from the Hive Logging section in Getting Started.

* [Parquet | https://cwiki.apache.org/confluence/display/Hive/Parquet]
* [Getting Started -- Hive Logging | https://cwiki.apache.org/confluence/display/Hive/GettingStarted#GettingStarted-HiveLogging]

Added TODOC2.1 and TODOC1.3 labels.

> Parquet uses java util logging. When java logging is not configured using default logging.properties
file, parquet's default fallback handler writes to STDOUT at INFO level. Hive writes all logging
to STDERR and writes only the query output to STDOUT. Writing logs to STDOUT may cause issues
when comparing query results. 
> If we provide default logging.properties for parquet then we can configure it to write
to file or stderr.
