> Similar to {{-fixReferenceFiles}}, HBCK should be able to sideline dangling HFile Links
as well. 
> We have seen a couple of cases, where due to HDFS-level fsck run which deleted files
with missing blocks, the cluster is left with dangling HFIle Links, and regions cannot be
opened because of these. Only a manual and error-prone finding and clearing of HFileLinks
can save the tables regions.
