Bikas Saha commented on HADOOP-8763:
------------------------------------
The following code seems to be an unrelated change? Also, do you mean BUILDIN
or BUILTIN?
{code}
+ // Empty name is invalid. However, LookupAccountName() function will return a
+ // false Sid, i.e. Sid for 'BUILDIN', for an empty name instead failing. We
+ // report the error before calling LookupAccountName() function for this
+ // special case.
+ //
+ if (wcslen(acctName) == 0)
+ return FALSE;
{code}
Do you see any unexpected behavior for users because of the following?
{code}
+On Linux, if a colon but no group name follows the user name, the group of\n\
+the files is changed to that user\'s login group. Windows has no concept of\n\
+a user's login group. So we do not change the group owner in this case.\n",
