             Summary: Fix HFile V1 Detector to handle AccessControlException for non-existant files
                 Key: HBASE-9509
                 URL: https://issues.apache.org/jira/browse/HBASE-9509
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.96.0
            Reporter: Himanshu Vashishtha
             Fix For: 0.98.0, 0.96.0


On some hadoop versions, fs.exists() throws an AccessControlException if there is a non-searchable inode in the file path. Versions such as 2.1.0-beta just returns false.
This jira is to fix HFile V1 detector tool to avoid making such calls.

See the below exception when running the tool on one hadoop version
