Dataflow job not completed/failed after workers are being started

Question

I have created a dataflow pipeline which read a file from Storage Bucket and just do a simple transform to the data (e.g: trim the spaces).

When I execute the dataflow job, the job started and log shows that the workers are started in a zone, but after that nothing happens. Job never get completed or failed. I had to manually stop the job.

Dataflow job has been executed by a service account having dataflow.worker role, dataflow.developer role and dataflow.objectAdmin role.

Please can someone suggest why the dataflow job is not being completed or why the job not executed after the worker started.

Answer 1

I found the problem. I was running the job in a region as where the VPC was in different region. Thus the worker did not able to spin up. Make the region same as of the VPC and then everything went well.
