title: How to maintain failure recovery during sqoop import Job
body: <p>We are planing to create Oozie job which run Sqoop command to import data from SQL server to HDFS on hourly basis. But we are facing challenge, how to get alert if that job fails in between and how sqoop will check which data imported successfully and which is still pending. Is there any process to maintain transactions and retry mechanism during sqoop import. And also we get alert on their failure.</p>
