Anu Engineer commented on HDFS-12345:

[~xkrogen] I have looked at the source and read the excellent blog that you 
wrote. Thank you. I am very impressed by this tool and I am +1 for making this 
tool to be part of Hadoop. The most important reason is that we will be able to 
make sure that this tool stays current with the code base.

It might lead to adding some simple "sanity check" type of unit tests though, 
so that we can detect it we have accidently broken this tool.

> To encourage getting the tool into the open for others to use as quickly as 
> possible, we went through our standard open sourcing process of releasing on 
> GitHub. However we are interested in the possibility of donating this to 
> Apache as part of Hadoop itself and would appreciate feedback on whether or 
> not this is something that would be supported by the community.
