Description

Extended HDFS filesystem attributes are exposed through the `getfacl` command.

It would be immensely help to have this information accessible via:

pyarrow.hdfs.HadoopFileSystem

 

Link to the official Hadoop docs where this is discussed in more detail:

https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/FileSystemShell.html#getfacl

Sample output from the *nix shell:

$ hadoop fs -getfacl /path/to/hdfs/dir
 # file: /path/to/hdfs/dir
 # owner: hive
 # group: hive
 user::rwx
 group:unix_group_with_acl_privs_defined:rwx
 group::---
 user:hive:rwx
 group:hive:rwx
 mask::rwx
 other::--x
