Description

GzipCodec has Java 6 specific code and it can be removed.

GzipCodec.java

      public static final String JVMVersion= System.getProperty("java.version");
      private static final boolean HAS_BROKEN_FINISH =
          (IBM_JAVA && JVMVersion.contains("1.6.0"));

Hadoop 2.7+ dropped Java 6 support.
