Subject [jira] [Created] (HBASE-17799) HBCK region boundaries check can return false negatives when IOExceptions are thrown
Date Fri, 17 Mar 2017 17:50:41 GMT
Esteban Gutierrez created HBASE-17799:
-----------------------------------------

             Summary: HBCK region boundaries check can return false negatives when IOExceptions
are thrown
                 Key: HBASE-17799
                 URL: https://issues.apache.org/jira/browse/HBASE-17799
             Project: HBase
          Issue Type: Bug
          Components: hbck
    Affects Versions: 2.0.0, 1.4.0, 1.3.1, 1.2.5
            Reporter: Esteban Gutierrez
            Assignee: Esteban Gutierrez


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.
