>             Project: Parquet
>          Issue Type: Bug
>          Components: parquet-mr
>    Affects Versions: 1.6.0
>         Environment: Versions: Impalad version 2.6.0-cdh5.8.5 RELEASE (build d460423934c1689082f6297101a45b28c49bd39f)

> Create table ignores table properties.
>  
> {{CREATE EXTERNAL TABLE db.test (}}{{  month INT}}
> {{)}}
> {{STORED AS PARQUET}}
> {{LOCATION 'hdfs://nn/user/user/test'}}
> {{TBLPROPERTIES (}}
> {{  'STATS_GENERATED_VIA_STATS_TASK'='true',}}{{'PARQUET.COMPRESSION'='GZIP',}}{{'PARQUET.VERSION'='PARQUET_2_0');}}
>  
> After inserting into this table with the following:
> {{INSERT INTO TABLE db.test}}
> {{SELECT * FROM db.source;}}
> The created Parquet files are SNAPPY compressed according to parquet-tools meta. Is there a difference which query engine is used? Impala or Hive? Should this be resulting GZIP compressed files or Parquet ignores TBLPROPERTIES?
