[GitHub] [beam] ibzib opened a new pull request #12250: [BEAM-10460] Limit SparkPortableExecutionTest to a single thread.

URL: https://github.com/apache/beam/pull/12250
Starting up multiple Spark clusters at a time uses a lot of memory. Also, using a thread pool (even an artificially limited thread pool) is closer to the actual usage of JobInvocation than direct executor service, which assigns work back to the calling thread.

For a normal cluster, yes. But I'm not sure if there's a way to do this with a "local" (embedded) cluster.

Might want to confirm deflaking. Merging despite my question because if it helps that's great.
