Wei-Chiu Chuang commented on HDFS-13830:
----------------------------------------

+1 

Thanks [~smeng]. 

Also checked compat guide line  since this patch changes the visibility of 
methods and static class fields of FileStatus, which is widely used and 
Public.Stable, it is essentially a compatible change. Under Hadoop 
compatibility guideline 
[http://hadoop.apache.org/docs/r3.0.3/hadoop-project-dist/hadoop-common/InterfaceClassification.html#Stable,]
 a compat change can be made between maintenance releases. (Note there's a typo 
being addressed by HADOOP-15705)

(Wish Yetus could detect Hadoop compatibility violation)
