Parquet table snappy compressed by default

[#1]

Hi,

1) If we create a table (both hive and impala)and just specify stored as parquet . Will that be snappy compressed by default in CDH?

2) If not how do i identify a parquet table with snappy compression and parquet table without snappy compression?.

Also how to specify snappy compression for table level  whiel creating and also at global level, even if nobody specified at table level (all table stored as parquet should be snappy compressed).

Please help

If the tables are created STORED AS PARQUET in Hive will they be using Snappy codec or not ?

According to cloudera most of the CDH component that usess parquet file not compressed by default. 

for ORC format 

CREATE TABLE testingsnappy_orc
STORED AS ORC
TBLPROPERTIES("orc.compress"="snappy")
AS SELECT * FROM sourcetable;

for Parquet format 

same but add the

 
TBLPROPERTIES ( "orc.compress"="SNAPPY" );

By default, in Hive, Parquet files are not written with compression enabled.

However, writing files with Impala into a Parquet table will create files with internal Snappy compression (by default).
