How to confirm my files are snappy compresses in hive?

[#1]

So I compressed my table in hive using snappy compression and it did get compress. The size was reduced.

But when i run hadoop fs -lsr /hive/user.db/table_name, I see no file extensions with .snappy.

I want to know if they really were snappy compressed or not?

If you describe the table in hive, you should be able to see the compression algorithm applied to the table:

hive> describe formatted <hive_table>;

I don't believe there is a quick way to see if it is compressed via HDFS.

Yup @Michael Young.

Another way I found was through

hadoop fs -text <file-location>

On the top of results, INFO compress.CodecPool: Got brand-new decompressor [.snappy] is written which I think is a confirmation that snappy compression is applied.
