> 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.
