Hi @prismalytics,

 

As documented in the Apache Github, we need to execute with hadoop jar command for a file on HDFS filesystem.

---
#Run from hadoop

See Commands Usage for command to use

hadoop jar ./parquet-tools-<VERSION>.jar <command> my_parquet_file.lzo.parquet
---

 

So could you please execute hadoop jar command as following?

 

hadoop jar /opt/cloudera/parcels/<CDH-VERSION>/jars/parquet-tools-<VERSION>.jar <command> <hdfs path to parquet file>

 

e.g.

hadoop jar /opt/cloudera/parcels/CDH-6.1.0-1.cdh6.1.0.p0.770702/jars/parquet-tools-1.9.0-cdh6.1.0.jar cat hdfs://tmp/1.parquet

 

Thanks and hope this helps,

Li
