Examples of org.apache.hadoop.hdfs.protocol.FsAclPermission

org.apache.hadoop.hdfs.protocol.FsAclPermission
HDFS permission subclass used to indicate an ACL is present. The ACL bit is not visible directly to users of {@link FsPermission} serialization. This isdone for backwards compatibility in case any existing clients assume the value of FsPermission is in a particular range.
