Validate compression type in HDFS

[#1]

Hi - i would like to see the compression used in apache parquet and avro file using simple commands in hadoop. can you please guide me...Say for example there is a file in hadoop which is a parquet fie and LZO compression was chosen while creating it by someone else. Now i would like to verify the same in HDFS. How will i do that?

You can use parquet-tools and avro-tools command to check the file metadata.

Use the meta option to extract the compression details. 

Refer https://github.com/apache/parquet-mr/tree/master/parquet-tools

Hope this helps,
