Description
tclemons@tutanota.com reported in email thread:
I've been attempting to migrate to the AWS2 SDK (version 2.24.0) on Apache Spark 2.4.7. However, when switching over to the new API and running it I keep getting the following exceptions:
2020-09-30 20:38:32,428 ERROR streaming.StreamingContext: Error starting the context, marking it as stopped org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 2.0 failed 4 times, most recent failure: Lost task 0.3 in stage 2.0 (TID 6, 10.42.180.18, executor 0): java.lang.NullPointerException at org.apache.beam.sdk.io.aws2.sqs.SqsUnboundedSource.lambda$new$e39e7721$1(SqsUnboundedSource.java:41)

Examining the source of SqsUnboundedSource reveals a lambda where it's trying to chain a few references:
read.sqsClientProvider().getSqsClient()
Which is odd as I explicitly set the client provider on the read transform. This was working well enough with the old SqsIO API to connect and process messages off the queue.
