Error at at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:93)

Hi All
I wrote an MR job to fetch url content from web. Also I am using
DBInputformat to fetch url and write the URL content to DB.

When I execute the job I am getting the following error.

Any clue on the cause or solution !!!
