   Hi @wchevreuil, couple of comments based on my test. 
   
   Unless the region is overlapped with other regions in meta, uses should use `assign '<region>'` command as a viable action to take because it generates a new empty region directory appropriately via `org.apache.hadoop.hbase.regionserver.HRegionFileSystem#writeRegionInfoFileContent`. 
   
   Otherwise, in a case where the region is overlapped with others in meta, we should remove the region's entry from meta as assuming it does not have valid data in HDFS.
   
   Thoughts?
