> HDFS-12911 modularization is introducing FileIDCollector interface for scanning the
files. That will help us to plugin different ways of scanning mechanisms if needed.
> For Internal SPS, we have INode based scanning. For external SPS, we should go via client
API scanning as we can not access NN internal structures. 
> This is the task to implement the scanning plugin for external SPS.
