Tsz Wo Nicholas Sze commented on HDFS-6153:
-------------------------------------------

This is an incompatible API change.  "fileId" and "childrenNum" cannot be added 
as required fields since it breaks API compatibility.  This change is already 
in some releases.  How do we fix it?

> Document "fileId" and "childrenNum" fields in the FileStatus Json schema
