-----------------------------------------------------------
[~elgoiri], just have one comment for this place:
{code:java}
+ /**
+ * Get the permissions for the parent of a child with given permissions. If
+ * the child has r--, we will set it to r-x.
+ * @param mask The permission mask of the child.
+ * @return The permission mask of the parent.
+ */
+ private static FsPermission getParentPermission(final FsPermission mask) {
+ FsPermission ret = new FsPermission(
+ applyExecute(mask.getUserAction()),
+ applyExecute(mask.getGroupAction()),
+ applyExecute(mask.getOtherAction()));
+ return ret;
+ }
{code}
When prepare to get parent permission, why not use the consistent way as that
in {{FSNamesystem}}, like this:
*FSDirMkdirOp.java*
{code:java}
private static PermissionStatus addImplicitUwx(PermissionStatus parentPerm,
PermissionStatus perm) {
FsPermission p = parentPerm.getPermission();
FsPermission ancestorPerm = new FsPermission(
p.getUserAction().or(FsAction.WRITE_EXECUTE),
p.getGroupAction(),
p.getOtherAction());
return new PermissionStatus(perm.getUserName(), perm.getGroupName(),
ancestorPerm);
}
{code}
But this won't affect the process of commit, I'd like to commit this shortly.
We can take a further look in follow-up JIRAs.
