I am looking for POM.xml for mapreduce program development. is there seperate repository detail available for teradata hadoop ? 
Can someone please help? Thank you.

What is Aster Express?

I'm using TDCH to export a hive data into teradata table. For this I need to specify the number of mappers to my TDCH job. So, my question is "is this number of mappers option we give to TDCH job is just a hint to TDCH? or number of mappers created by TDCH will always be equal to number of mappers given in the option" (of the TDCH job)?

Hadoop MapReduce programmers often find that it is more convenient and productive to have direct access from their MapReduce programs to data stored in a RDBMS such as Teradata Enterprise Data Warehouse (EDW) because:

  1. There is no benefit to exporting relational data into a flat file.
  2. There is no need to upload the file into the Hadoop Distributed File System (HDFS).
  3. There is no need to change and rerun the scripts/commands in the first two steps when they need to use different tables/columns in their MapReduce programs.
