---------------------------------
Summary: Use HDFS ACL to give user the ability to read snapshot
directly on HDFS
Key: HBASE-18659
URL: https://issues.apache.org/jira/browse/HBASE-18659
Project: HBase
Issue Type: New Feature
Reporter: Duo Zhang
On the dev meetup notes in Shenzhen after HBaseCon Asia, there is a topic about
the permission to read hfiles on HDFS directly.

For client-side scanner going against hfiles directly; is there a means of
being able to pass the permissions from hbase to hdfs?

And at Xiaomi we also face the same problem. {{SnapshotScanner}} is much faster
and consumes less resources, but only super use has the ability to read hfile
directly on HDFS.
So here we want to use HDFS ACL to address this problem.
https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsPermissionsGuide.html#ACLs_File_System_API
The basic idea is to set acl and default on the table directory on HDFS for the
users who have the permission to read the table on HBase.
Suggestions are welcomed.
