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.
