It is not a concern. There's no way for you to remove it. It's
caused by code in Hadoop complaining at the way Pig interacts with it.
WARN org.apache.hadoop.mapred.JobClient - Use GenericOptionsParser
for
parsing the arguments. Applications should implement Tool for the
same.
And I am also I see an INFO message, what does this mean ?

er - Cannot get jobid for this job
What version are you using? Pig gets the jobid from Hadoop when it
submits the job. Sometimes Hadoop doesn't return the jobid soon
enough and then Pig complains (which is what you're seeing). In later
versions we've improved this but not removed it entirely. One way or
another it isn't an issue except that if you want to look up your job
on your Job Tracker's GUI or kill the job you don't have the job id.
