------------------------------------
Attachment: HADOOP-14820-006.patch
HADOOP-14820 patch 006
* fix line width on TestAzureFileSystemInstrumentation comment
* in TestNativeAzureFileSystemAuthorization , modify new test to not create the
dir childpath2, so that creating childpath3 forces the scan to go two levels up
before finding the first directory & its permissions.
Tested against Azure ireland: {{TestNativeAzureFileSystemAuthorization}} with
build set to security & auth; TestAzureFileSystemInstrumentation with those
options unset.
This is what I propose to commit if yetus is happy

> No authorization checks should be made when a user tries to create (mkdirs
> -p) an existing folder hierarchy.
> For example, if we start with _/home/hdiuser/prefix_ pre-created, and do the
> following operations, the results should be as shown below.
> {noformat}
> hdiuser@hn0-0d2f67:~$ sudo chown root:root prefix
> hdiuser@hn0-0d2f67:~$ sudo chmod 555 prefix
> hdiuser@hn0-0d2f67:~$ ls -l
> dr-xr-xr-x 3 root root 4096 Aug 29 08:25 prefix
> hdiuser@hn0-0d2f67:~$ mkdir -p /home
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser/prefix
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser/prefix/1
> mkdir: cannot create directory â/home/hdiuser/prefix/1â: Permission denied
> The first three mkdirs succeed, because the ancestor is already present. The
> fourth one fails because of a permission check against the (shorter) ancestor
> (as compared to the path being created).
