配置更改

spark集群主要涉及到如下配置文件的变更

spark-default.conf
spark-env.sh
slaves

spark-default.conf

spark.master            spark://SZB-L0045546:7077
spark.executor.memory   4g

spark.scheduler.mode    FIFO
spark.shuffle.compress  true
spark.ui.port           4040

spark.eventLog.dir      /wls/oracle/bigdata/spark/sparkeventlog
spark.kryoserializer.buffer 512m
spark.rpc.numRetries    5
spark.port.maxRetries   16
spark.rpc.askTimeout    120s
spark.network.timeout   120s
spark.rpc.lookupTimeout  120s

spark.executor.extraJavaOptions -XX:+UseG1GC -XX:InitiatingHeapOccupancyPercent=40 -XX:G1ReservePercent=10 -XX:G1HeapRegionSize=8M -XX:MaxPermSize=300M -XX:+PrintReferenceGC -XX:+PrintAdaptiveSizePolicy -XX:+UnlockDiagnosticVMOptions -XX:+G1SummarizeConcMark -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps

spark-env.sh

export SPARK_CLASSPATH="$SPARK_CLASSPATH:$SPARK_HOME/lib/*:$SPARK_CLASSPATH

其中$SPARK_HOME/jars/为spark系统自带的jar包,而$SPARK_HOME/lib/为我们自定义的外部jar包，如kafka,mongo等应用相关jar包

slaves
