We're seeing 'Exit Code 137' regularly in the batch tests, which means that the host OS killed the test process due to memory exhaustion. Disabling parallel test execution to avoid those memory problems. --- runners/flink/job-server/flink_job_server.gradle | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/runners/flink/job-server/flink_job_server.gradle b/runners/flink/job-server/flink_job_server.gradle index 0611969..8f6a703 100644 --- a/runners/flink/job-server/flink_job_server.gradle +++ b/runners/flink/job-server/flink_job_server.gradle @@ -120,7 +120,7 @@ def portableValidatesRunnerTask(String name, Boolean streaming) { jobServerDriver: "org.apache.beam.runners.flink.FlinkJobServerDriver", jobServerConfig: "--clean-artifacts-per-job,--job-host=localhost,--job-port=0,--artifact-port=0", testClasspathConfiguration: configurations.validatesPortableRunner, - numParallelTests: 2, + numParallelTests: 1, pipelineOpts: pipelineOptions, environment: BeamModulePlugin.PortableValidatesRunnerConfiguration.Environment.EMBEDDED, testCategories: {
