Working with Ozone File System (o3fs)

The Ozone File System (o3fs) is a Hadoop-compatible file system. Applications such as Hive, Spark, YARN, and MapReduce run natively on o3fs without any modifications.

The Ozone File System resides on a bucket in the Ozone cluster. All the files created through o3fs are stored as keys in that bucket. Any keys created in the particular bucket without using the file system commands are shown as files or directories on o3fs.
