bb commented on ARROW-6756:
---------------------------
All the libhdfs docs i found said:
{quote}The libhdfs APIs are a subset of the [Hadoop FileSystem
APIs|https://hadoop.apache.org/docs/current/api/org/apache/hadoop/fs/FileSystem.html].
{quote}
And goes on to say that:
{quote}The header file for libhdfs describes each API in detail and is
available in {{$HADOOP_PREFIX/src/c++/libhdfs/hdfs.h}}
{quote}
I grep'd hdfs.h and didnt see any explicit "acl" reference nor could I find it
in the hadoop github repo but it's possible that the API is referenced under
another name or I am looking in the wrong places?

> Key: ARROW-6756
> URL: https://issues.apache.org/jira/browse/ARROW-6756
> Project: Apache Arrow
> Issue Type: Wish
> Components: Python
> Affects Versions: 0.13.0
> Reporter: bb
> Priority: Major
> Labels: arrow, hdfs, pyarrow
>
> Extended HDFS filesystem attributes are exposed through the `getfacl` command.
> It would be immensely help to have this information accessible via:
> {code:java}
> pyarrow.hdfs.HadoopFileSystem{code}
>
> 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:
> {code:java}
> $ 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
