body: <p>My use case:</p>
  
  <p>Day by day hourly tables gets created in mysql db. I need to move them everyday to HDFS using Sqoop and process the HDFS data using Impala. </p>
  
  <p>How to write a shell script or job only to move the tables data that are newly created to HDFS(existing file system) periodically?</p>
