org.apache.http.conn.ConnectTimeoutException: What does this mean and how can we resolve it.

[cmilligan]

My team has run into getting this error pretty frequently on one of our larger jobs. I've set out retry policy to 5 and that seems to fix it and keep the job going. It seems like it's unable to pick up the task immediately but can after it's completed with some of the other tasks running at the same time.

We share our cluster as part of a larger team and have jobs running constantly but this seems to be the only one that fails this way. Is there anything we can do to resolve getting this error so much?

Hey @Coleman Milligan​ ,

I also faced this type of issue many times

you can add the below configuration in your cluster and it should work.

spark.executor.heartbeatInterval 60s

spark.network.timeout 120s

For more details, you can explore this doc - https://spark.apache.org/docs/latest/configuration.html

you will get all details about the above 2 configuration
