can any anyone tell me what i need to do to run the Sqoop export.

below are the console logs

hdfs@node-2:/$ sqoop export --connect jdbc:mysql://kraptor/kraptor  --username root --password-file file:///var/lib/hadoop-hdfs/sqoop.password  --table Demo_blog --update-key id  --update-mode updateonly --export-dir /user/hdfs/demoblog.csv -m4  --lines-terminated-by '\n' --input-fields-terminated-by ',' --driver com.mysql.jdbc.Driver;
