Accessing local files in Ozone

You can access files in Ozone on a local file system using hdfscli. This method works with both legacy engines and runtime sessions.

The following commands enable a CML session to connect to Ozone using the o3fs protocol.

1. Put the input file into Ozone:

   hdfs dfs -put data/jedi_wisdom.txt o3fs://hivetest.s3v.o3service1/spark

2. List the files in Ozone:

   hdfs dfs -ls o3fs://hivetest.s3v.o3service1/

3. Download file from ozone to local:

   hdfs dfs -copyToLocal o3fs://hivetest.s3v.o3service1/spark data/jedi_wisdom.txt
