我已经升级了 Spark 并尝试在 YARN 上运行已经存在的 Spark Streaming 应用程序（通过流接受文件名，然后从 HDFS 读取，使用 rdd 和数据帧操作进行转换，最后分析的数据集持久化到 HBase），即失败并且无法解决问题。
环境详情如下
使用版本
平台
操作系统：RHEL 6.6、128GB RAM、42TB HDD、32 核
Java：1.8.0_25
Scala：2.11
Hadoop：2.7.7
Spark：2.4.6 with Hadoop 2.7 binaries
HBase：1.4.12
升级后无法使用
Spark：3.0.0 与 Hadoop 2.7 二进制文件
使用 Scala 2.12 编译相同的代码，根据 Spark 3.0.0 的要求，根据版本更改进行了一些小的更改，没有逻辑更改。
所需的 YARN 配置
<property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle,spark_shuffle</value> </property> <property> <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name> <value>org.apache.hadoop.mapred.ShuffleHandler</value> </property> <property> <name>yarn.nodemanager.aux-services.spark_shuffle.class</name> <value>org.apache.spark.network.yarn.YarnShuffleService</value> </property> <property> <name>spark.shuffle.service.port</name> <value>7337</value> </property>
启动作业时通过 Spark 配置
spark.app.name=Ingestion
spark.eventLog.enabled=true
spark.yarn.historyServer.address=${hadoopconf-yarn.resourcemanager.hostname}:18088
spark.eventLog.dir=hdfs:///user/hduser/applicationHistory
spark.submit.deployMode=cluster
spark.driver.memory=1GB
spark.driver.cores=1
spark.executor.memory=5GB
spark.executor.cores=5
spark.dynamicAllocation.enabled=true
spark.shuffle.service.enabled=true
spark.dynamicAllocation.minExecutors=1
spark.sql.shuffle.partitions=2001
spark.logging.level=INFO
spark.serializer=org.apache.spark.serializer.KryoSerializer
spark.yarn.archive=hdfs:///spark-3.0.0-bin-hadoop2.7-jars.zip
spark.ui.killEnabled=false
spark.driver.memoryOverhead=512
spark.executor.memoryOverhead=1024
spark.yarn.maxAppAttempts=4
spark.yarn.am.attemptFailuresValidityInterval=1h
问题
同一段代码正在使用具有相同 Hadoop、YARN、Spark 配置集的 spark 版本 2.4.4、2.4.5、2.4.6。当我升级到 spark 3.0.0 时，代码开始失败并出现以下异常。尝试过多次调整，例如增加资源、减少分区等，但没有运气。已通过 telnet 检查端口 7337，它已打开并正在侦听。经过一周的调试，无法找到任何解决方案，似乎没有理由关闭随机端口连接。
处理几乎没有 50 MB 的数据集。相同的代码能够处理与 Spark 2.4.x 具有完全相同配置的超过 300 MB 的数据。这很奇怪！
