https://community.qlik.com/t5/Talend-Studio/Parallelize-the-subjob/m-p/2222335#M15989 <P>I need to create a job which will ingest list of tables by sqooping data from source (RDBMS) to hadoop then to hive.</P> <P>I put list of tables in a file, read and iterate it to ingested.</P> <P>Because I have about 300+ tables to ingest, so it will take time if it ingested just by a process.
