kamilwu commented on issue #11193: [BEAM-9550] Increase JVM Metaspace size for the TaskExecutors. URL: https://github.com/apache/beam/pull/11193#issuecomment-603366145 @mxm Could you take a look at this? Our python tests, running on Flink cluster on YARN, are flaky since we updated Flink version to 1.10. Most of the time the pipeline is being aborted by this exception: `OutOfMemoryError: Metaspace`, for example here [1] and here [2]. I tried to increase JVM metaspace size (as suggested here: [3]), but it didn't work. Do you have ideas what's going wrong?
