Ayush Saxena commented on HDFS-14848:
-------------------------------------
Thanx [~akki261001] for putting this up.
Actually the reason for ACE is :
{code:java}
try {
checkTraverse(pc, iip, dirOp);
} catch (ParentNotDirectoryException pnde) {
if (!isCreate) {
throw new AccessControlException(pnde.getMessage());
}
throw pnde;
}
{code}
Ideally it was to prevent {{ParentNotDirectoryException}}, but ACE doesn't
seems to be an ideal substitute to it. Changing to FileNotFoundException would
be a better choice, it could atleast be near the context. Anyway ACE has
different handling too, as in {{FsNamesystem}} for audit logging only ACE is
caught, so here unnecessarily this will also get caught.
will upload patch changinf to FNF.
