title: What is --direct mode in sqoop?
body: <p>As per my understanding sqoop is used to import or export table/data from the Database to HDFS or Hive or HBASE.</p>
  
  <p>And we can directly import a single table or list of tables. Internally mapreduce program (i think only map task) will run. </p>
  
  <p>My doubt is what is sqoop direct and what when to go with sqoop direct option?</p>
