>                 Key: HDFS-5619
>                 URL: https://issues.apache.org/jira/browse/HDFS-5619
>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>          Components: namenode
>    Affects Versions: HDFS ACLs (HDFS-4685)
>            Reporter: Chris Nauroth
>            Assignee: Haohui Mai

> Implement a new edit log opcode, {{OP_SET_ACL}}, which fully replaces the ACL of a specific inode.  For ACL operations that perform partial modification of the ACL, the NameNode must merge the modifications with the existing ACL to produce the final resulting ACL and encode it into an {{OP_SET_ACL}}.
