How to uncompress compressed data in Spark/SparkSQL?


#1

Hi all,

Is anyone uncompressed compressed data in Spark of Parquet file? Using below:
sqlContext.setConf(“spark.sql.parquet.compression.codec”, “uncompressed”)

Also, Snappy is default compression in Spark/SparkSQL. But someone referred gzip is default. Can you please confirm which is correct default compression in Spark/SparkSQL?
Thanks
