Subject [jira] [Created] (HBASE-6686) HFile Quaranatine fails with missing dirs in hadoop 2.0

Jonathan Hsieh created HBASE-6686:
-------------------------------------

             Summary: HFile Quaranatine fails with missing dirs in hadoop 2.0 
                 Key: HBASE-6686
                 URL: https://issues.apache.org/jira/browse/HBASE-6686
             Project: HBase
          Issue Type: Bug
          Components: hbck
    Affects Versions: 0.92.2, 0.96.0, 0.94.2
            Reporter: Jonathan Hsieh
             Fix For: 0.92.2, 0.96.0, 0.94.2


Two unit tests fail because listStatus's semantics change between hadoop 1.0 and hadoop 2.0.
 (specifically -- hadoop 1.0 returns empty array if used on dir that does not exist, but hadoop
2.0 throws FileNotFoundException).

here's the exception:
