Edward Capriolo updated HIVE-752:
---------------------------------

    Attachment: hive-752.diff

Not sure if this fixes all issues but adds a test case for some shim validity. Fixes the class
name error. Will add more later.

> Encountered ClassNotFound exception (for class: org.apache.jetty.hive.shims.Jetty18Shims)
when trying to start HWI server on Hadoop 18.
> It appears that the class ShimLoader (org.apache.hadoop.hive.shims.ShimLoader) is referring
to incorrect classes as below:
> static {
>     JETTY_SHIM_CLASSES.put("0.17", "org.apache.jetty.hive.shims.Jetty17Shims");
>     JETTY_SHIM_CLASSES.put("0.18", "org.apache.jetty.hive.shims.Jetty18Shims");
>     JETTY_SHIM_CLASSES.put("0.19", "org.apache.jetty.hive.shims.Jetty19Shims");
>     JETTY_SHIM_CLASSES.put("0.20", "org.apache.jetty.hive.shims.Jetty20Shims");
>   }
> however, I think it should be as below:
>  static 
>   {
> 	  JETTY_SHIM_CLASSES.put("0.17", "org.apache.hadoop.hive.shims.Jetty17Shims");
> 	  JETTY_SHIM_CLASSES.put("0.18", "org.apache.hadoop.hive.shims.Jetty18Shims");
> 	  JETTY_SHIM_CLASSES.put("0.19", "org.apache.hadoop.hive.shims.Jetty19Shims");
> 	  JETTY_SHIM_CLASSES.put("0.20", "org.apache.hadoop.hive.shims.Jetty20Shims");
>   } 
> Wondering if anybody else encountered this.
