Chris Nauroth updated HDFS-5594:
--------------------------------
Attachment: HDFS-5594.3.patch
Here is patch version 3 with the following changes:
# Previously, {{Acl}} contained the associated file/owner/group. This would
have made the class cumbersome to use in the NameNode implementation, where we
want to conserve memory by referencing the same {{Acl}} from multiple files.
I've removed file/owner/group.
# However, we still do need a way to get the association between an ACL and a
file/owner/group. The getfacl CLI prints this information, and clients who do
a recursive get also need a way to link each ACL in the result set back to its
file. To support this, I've introduced a new {{AclStatus}} class that contains
ACL, file, owner and group.
# {{AclStatus}} is returned from {{listAclStatus}}, which was previously called
{{getAcls}}. I did this rename for consistency with existing methods like
{{listStatus}}.
# It looks like the getfacl command traditionally prints the additional flags
on the file too, like sticky bit. To support this, I've added sticky bit as a
member of {{Acl}}. That's also helpful for the NameNode implementation, where
we'll need a distinct {{Acl}} instance for different sticky bit settings even
if the ACL entries are otherwise identical.
