[jira] [Created] (HIVE-5188) MR job launched through WebHCat fails to find additional jars in classpath

             Summary: MR job launched through WebHCat fails to find additional jars in classpath
                 Key: HIVE-5188
                 URL: https://issues.apache.org/jira/browse/HIVE-5188
             Project: Hive
          Issue Type: Bug
          Components: WebHCat
    Affects Versions: 0.12.0
            Reporter: Deepesh Khandelwal


When running MR job using jar (compiled with external dependencies eg. HCatInputFormat, HCatOutputFormat) through WebHCat the job fails complaining about missing HCat classes. I did pass those through the libjars argument but it seems that we run the hadoop jar locally on the tasktracker node and so it doesn't have the additional classes in the HADOOP_CLASSPATH. To get around the problem I had to explicitly add the additional jar dependencies in the hadoop-env.sh.
