spark history server异常

现象：spark 日志文件突然新增了很多.hprof文件，

查找日志spark配置参数spark_log_dir进入日志目录：

查看historyServer日志：

bash 复制代码

Spark Command: /usr/lib/jvm/java-1.8.0/bin/java -cp /opt/apps/JINDOSDK/jindosdk-current/lib/*:/etc/taihao-apps/spark-conf/:/opt/apps/SPARK3/spark-current/jars/*:/etc/taihao-apps/hadoop-conf/ -XX:+ExitOnOutOfMemoryError -XX:OnOutOfMemoryError=kill -9 %p -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/taihao-apps/spark/ -Dlog4j.configuration=file:/etc/taihao-apps/spark-conf/spark-daemon-log4j.properties -Dspark.log.dir=/var/log/taihao-apps/spark -Dspark.log.file=spark-history-server.log -Xloggc:/var/log/taihao-apps/spark/spark-history-gc.log -XX:+IgnoreUnrecognizedVMOptions -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=128M -Xmx1g org.apache.spark.deploy.history.HistoryServer

发现是history Server服务一直启动oom异常

重启一下：

bash 复制代码

yarn --daemon start timelineserver

或者：
yarn-daemon start timelineserver

重启无效，

定位配置参数发现spark历史任务日志太多，一直没清理

修改配置参数：

bash 复制代码

spark.history.fs.cleaner.enabled = true

spark_history_daemon_memory = 8g

spark_thrift_daemon_memory = 4g

成功
