Description

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.
