Inspect Parquet from command line

You can use parquet-tools with the command cat and the --json option in order to view the files without a local copy and in the JSON format.

Here is an example:

parquet-tools cat --json hdfs://localhost/tmp/save/part-r-00000-6a3ccfae-5eb9-4a88-8ce8-b11b2644d5de.gz.parquet

This prints out the data in JSON format:

{"name":"jane","age":30,"city":"new york"}

Disclaimer: this was tested in Cloudera CDH 5.12.0
