Thanks a lot Venkat for the information.
Now I will use Apache Hadoop 2.4.0 and Hortonworks Connector for Teradata v1.3 for HDP2.1
I will refer the increment import section from the documentation.
Just for curiosity wanted to know whether the Sqoop ONLY command line options for incremental import be supported as well in this case or I need to follow the one mentioned in the documentation of Hortonworks Connector ?
