Hi nirmal,

DAS features such as scripts scheduling, purging,etc are used to submit the
jobs (only spark queries) to external spark cluster, rather those DAS
features jars doesn't need to exists within the external spark cluster
instance. For example, if we consider spark script scheduled execution
scenario which uses Task OSGI services,  and the task triggering will be be
occurred wihing DAS node (OSGI env), furthermore when the spark is
configured externally the job will be handed over to the external cluster,
and then results will be given back to DAS node. Therefore I don't think
any of the DAS features jars other than DAL feature jars will be required
to be inside the external spark cluster.

Can you please explain more on what is your usecase? And how you have
configured the setup with DAS features?

Thanks,
Sinthuja.
