> The motivation of introducing the HardLink operation/api in HDFS is to get a full copy
of the file without copying the bytes. 
> So users/applications can create multiple hard links to the same source file instantly.

> And HBase can make full use of the hard-link to generate the in-cluster backup snapshot
instantly.
