我们已经用图1.5-debian10创建了gcpdataproc集群。群集创建成功。
spark版本是 2.4.7 并在图像上方的dataproc集群上运行。
dataproc群集软件配置：
群集属性：

softwareConfig:
    imageVersion: 1.5.23-debian10
    properties:
      capacity-scheduler:yarn.scheduler.capacity.maximum-am-resource-percent: '0.9'
      capacity-scheduler:yarn.scheduler.capacity.resource-calculator: org.apache.hadoop.yarn.util.resource.DominantResourceCalculator
      capacity-scheduler:yarn.scheduler.capacity.root.default.ordering-policy: fair
      core:fs.gs.block.size: '134217728'
      core:fs.gs.metadata.cache.enable: 'false'
      core:hadoop.ssl.enabled.protocols: TLSv1,TLSv1.1,TLSv1.2
      dataproc:dataproc.conscrypt.provider.enable: 'false'
      dataproc:job.history.to-gcs.enabled: 'true'
      mapred:mapreduce.jobhistory.done-dir: gs://</bucketName>/mapreduce/mapreduce-job-history/done
      mapred:mapreduce.jobhistory.intermediate-done-dir: gs://<bucketName>/mapreduce-job-history/intermediate-don
      spark:spark.eventLog.dir: gs://<bucketname>/spark-job-history/events
      spark:spark.executor.cores: '8'
      spark:spark.executor.instances: '2'
      spark:spark.executor.memory: 8379m
      spark:spark.executorEnv.OPENBLAS_NUM_THREADS: '1'
      spark:spark.history.fs.logDirectory: gs://<bucketname>/spark-job-history
      spark:spark.scheduler.mode: FAIR
      spark:spark.sql.cbo.enabled: 'true'

设置的变通方法 spark.eventLog.enabled false ，在spark submit命令中，作业可以正常工作。但我们以后将无法访问spark history server来分析日志。
错误：
