As Spark is lazy evaluated, using only small clusters for read and large ones for writes is not something that will happen.The data is read when you apply an action (write f.e.).That being said: I have no knowledge of a bug in Databricks on clusters...
Hi everybody,I'm trying to setup a connection between Databricks' Notebooks and an external PostgreSQL database through a SSH-tunnel. On a single-node cluster, this is working perfectly fine. However, when this is ran on a multi-node cluster, this co...
I doubt it is possible.The driver runs the program, and sends tasks to the executors. But since creating the ssh tunnel is no spark task, I don't think it will be established on any executor.
