Possibly try using the Oozie deployer available as a panel in the Studio. You can set a username. Oozie is required to be running on Hadoop.
My config within TOS4BD is:
Name node end point: hdfs://talend-hdp-all
Job tracker end point: talend-hdp-all:50300
Oozie end point:http://talend-hdp-all:11000/oozie
Deploying job to Hadoop...
Can not access Hadoop File System with user hdfs!
Server IPC version 7 cannot communicate with client version 4
