我的Spark机群是部署在Yarn上的,因为之前Yarn的部署只是简单的完全分布式,但是后来升级到HA模式,一个主NN,一个备NN,那么Spark HistoryServer的配置也需要相应的做修改,因为不做修改会报错

1 非Hadoop HA下Spark HistoryServer配置
1.1 配置spark-defalut.conf
spark.eventLog.enabled true spark.eventLog.dir hdfs://1421-0002:9000/spark/sparklogs
spark.yarn.historyServer.address 1421-0002:18080
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.executor.instances 4
其中配置了日志文件存储的HDFS的路径,还有Spark history server的地址
1.2 配置spark-env.sh
#指定logDirectory,在start-history-server.sh时就无需再显示的指定路径 export SPARK_HISTORY_OPTS="-Dspark.history.retainedApplications=10 -Dspark.history.fs.logDirectory=hdfs://1421-0002:9000/spark/sparklogs"
其中指定了日志文件存储的HDFS路径,那么每次启动就不需要加这个参数了
1.3 启动Spark History Server
start-history-server.sh
2 Hadoop HA下,Spark HistoryServer配置
2.1 修改spark-env.sh
#指定logDirectory,在start-history-server.sh时就无需再显示的指定路径 export SPARK_HISTORY_OPTS="-Dspark.history.retainedApplications=10 -Dspark.history.fs.logDirectory=hdfs://hadoop-cluster/spark/sparklogs"
这里将HDFS的路径修改了,因为之前只有一个NN,HA的情况下,指定了两个,所以将1421-0002:9000替换成hadoop-cluster(hadoop/etc/hadoop/hdfs-site.xml 中dfs.nameservices配置的值),不需要指定端口
