The notebook1003/4 hosts were decommed in T249752. The idea is to re-purpose those hosts to:
- an-launcher1002 - replacement of an-launcher1001, more ram/cores to avoid bottlenecks when lot of jobs are running (like the beginning of the month with sqoop).
- an-airflow/scheduler - dedicated node for Airflow (or any similar scheduling tool that we'll choose).
The tricky part is to rename DNS hostnames in dns/puppet to avoid troubles, that needs to be done with extreme care.
