How to introduce delay time between retry attempts for spark streaming job

sat_046 — Wed, 01 Feb 2023 11:48:14 GMT

We are running a spark streaming job which reads data from kafka and writes to RDBMS. We dont want this job to fail easily due to minor fluctuations in cluster health/issue. Write now spark job has configuration to retry 5 attempts before the whole job fails. But all these retries are happening in quick succession , one after another. Is there a way we can put some delay/sleep time between retry attempts for this job?

Hi @sat_046

I don't think we have a specific configuration parameter to handle the task retry attempts with some delay. But we have a parameters to blacklist the node if the task is failed with some no of attempts in the node.

Hi @sat_046

As i mentioned earlier comment, unfortunately it is not possible to delay the tasks. You can find the Spark code when tasks failed.
