> When enabled, HBaseFsck#checkRegionBoundaries will crawl all HFiles across all namespaces
and tables when {{-boundaries}} is specified. However if an IOException is thrown by accessing
a corrupt HFile, an un-handled HLink or by any other reason, we will only log the exception
and stop crawling the HFiles and potentially reporting the wrong result.
