Description

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.
