Chris Douglas commented on HDFS-11084:
--------------------------------------

Sorry [~jojochuang], I'd missed your comment on HADOOP-13508 and this issue.

Can you be more specific? You seem to have traced a bug, but your report 
contains too few details to reconstruct your analysis. Did HADOOP-13508 cause a 
regression? Or are you suggesting backporting it to solve a similar issue in 
branch-2?

>             Project: Hadoop HDFS
>          Issue Type: Bug

>    Affects Versions: 2.8.0

> HDFS-10505 added a new feature OIV ReverseXML processor to generate a fsimage 
> from a xml file. However, if the files/directories in it has sticky bit, 
> ReverseXML processor can not recognize it due to HADOOP-13508.
> It seems HADOOP-13508 is an incompatible change in Hadoop 3. Would it be 
> reasonable to add an overloaded FsPermission constructor that uses RawParser 
> so that it reads sticky bits correctly? Or is it reasonable to backport 
> HADOOP-13508 to branch-2?
