      Description

      Original issue in HIVE-6900 :

      The signature for HostUtil.getTaskLogUrl has changed between Hadoop-2.3 and Hadoop-2.4.
      
      Code in shims/0.23/src/main/java/org/apache/hadoop/hive/shims/Hadoop23Shims.java works with Hadoop-2.3 method and causes compilation failure with Hadoop-2.4.
      

      The issue with HIVE-6900 is still not completely fixed, in that compilation succeeds, but this fails now at runtime because https://issues.apache.org/jira/secure/attachment/12651497/MAPREDUCE-5830.patch was committed in hadoop - The result is that our reflection check to see if the 23_METHOD exists succeeds, which means 23_METHOD will not be null, and 24_METHOD will be null, and thus, at runtime, we will wind up calling 23_METHOD. If hadoop had not "fixed" this bug, with this fix, our shim works, but with their fix, it looks like we still have a runtime problem.
