Hi team, I’m trying to create a pipeline in Apache Hop (running on *Windows*) and submit it to a remote Flink cluster (running on *Linux*). However, I’m encountering a NULL POINTER EXCEPTION when attempting to execute it. After consulting the user mailing list, I learned that submitting to Flink remotely doesn’t seem to work. So, I am now trying to submit the pipeline on the same machine. Before proceeding, I have a few questions:
- Does "same machine" mean that both Apache Hop and Flink should run on the same server(*linux*), or can they be on different servers(*linux*)? - If they need to be on the same machine, should Apache Hop run on the same server as the Flink master, or is it okay to submit from any Flink node? - I am also setting up Apache Hop Web using Docker on a Linux server, and I expect to submit pipelines to Flink from there. Is this the correct approach? - Is there any difference between using Apache Hop’s desktop application and Apache Hop Web? - Finally, can Apache Hop handle stopping and canceling jobs, or is it only capable of submitting jobs to Flink? Thanks in Advance
