Description

This patch will include the core logic for modification of ACLs. This includes support for all user-facing APIs that modify ACLs. This will cover access ACLs, default ACLs, automatic mask calculations, automatic inference of unprovided default ACL entries, and validation to prevent creation of an invalid ACL.

Issue Links

• breaks: HDFS-5737 Replacing only the default ACL can fail to copy unspecified base entries from the access ACL.
• is duplicated by: HDFS-5617 NameNode: enforce maximum number of ACL entries.
• is related to: HDFS-5595 NameNode: implement AclManager as abstraction over INode ACL Map.
