Spark not using spark.sql.parquet.compression.codec
<p>I'm comparing spark's parquets file vs apache-drill's.
Drill's parquet are way more lightweight then spark's. Spark uses GZIP as compression codec as default, for experimenting I tried to change it to
snappy : same size
uncompressed: same size
lzo : exception</p>

<p>I tried both ways:</p>

<pre><code>sqlContext.sql("SET spark.sql.parquet.compression.codec=uncompressed")
sqlContext.setConf("spark.sql.parquet.compression.codec.", "uncompressed")
</code></pre>

<p>But seems like it dosen't change his settings</p>
