Description

Currently, the ACL RPC defines ACL entries with required fields for name and permissions. These fields actually need to be optional. The name can be null to represent unnamed ACL entries, such as the file owner or mask. Permissions can be null when passed in an ACL spec to remove ACL entries via FileSystem#removeAclEntries.
