5. spark

spark当前可解压即用，yarn-client模式无需分发，只需修改客户端若干配置；

  • spark-1.1.0 on yarn的几个配置说明如下：
  • vim spark-env.sh
  • MASTER：部署模式，yarn-client/yarn-cluster/local
  • HADOOP_CONF_DIR：（必填）hadoop配置文件目录
  • SCALA_HOME：scala安装路径
  • SPARK_EXECUTOR_INSTANCES：spark申请的yarn worker总数
  • SPARK_EXECUTOR_CORES：每个worker申请的vcore数目
  • SPARK_EXECUTOR_MEMORY：每个worker申请的内存大小
  • SPARK_DRIVER_MEMORY：spark申请的appMaster内存大小
  • SPARK_YARN_APP_NAME：yarn中显示的spark任务名称
  • SPARK_YARN_QUEUE：spark任务队列
  • SPARK_SUBMIT_LIBRARY_PATH：spark任务执行时需要的库目录，如hadoop的native目录
  • SPARK_CLASSPATH：spark任务的classpath
  • SPARK_JAVA_OPTS：JVM进程参数，如gc类型、gc日志、dmp输出等
  • SPARK_HISTORY_OPTS：spark history-server配置参数，一般需要指定webUI端口、记录个数以及Event存储目录等
  • vim spark-defaults.conf
  • spark.local.dir：spark任务执行时的本地临时目录
  • spark.yarn.executor.memoryOverhead：每个worker的堆外内存大小，单位MB，yarn模式下需配置以防止内存溢出
  • spark.eventLog.enabled：是否记录Spark事件，用 于应用程序在完成后重构webUI
  • spark.eventLog.dir：保存日志相关信息的路径，可以是hdfs://开头的HDFS路径，也可以是file://开头的本地路径，都需要提前创建
  • spark.eventLog.compress：是否压缩记录Spark事件，前提spark.eventLog.enabled为true，默认使用snappy
  • 启停thrift-server：

使用spark-sql/thrift-server组件前需将hive-site.xml复制到$SPARK_HOME/conf目录下以使用hive的元数据和若干配置如server端口，可能需要去掉其中的一些多余或不支持的配置项，请留意；

    $SPARK_HOME/sbin/start-thriftserver.sh

    $SPARK_HOME/sbin/stop-thriftserver.sh

  • 启停history-server：
  • $SPARK_HOME/sbin/start-history-server.sh
  • $SPARK_HOME/sbin/stop-history-server.sh
  • 注意：
  1. 如hadoop中启用了lzo压缩需将hadoop-lzo-*.jar复制到SPARK_HOME/lib/目录下；
  2. SPARK-1.1.0版本中spark-examples-*.jar关联的thrift版本与spark-assembly-*.jar不一致，需删除；
  • 配置样例：

spark-env.sh

    MASTER="yarn-client"

    SPARK_HOME=/home/ochadoop/app/spark

    SCALA_HOME=/home/ochadoop/app/scala

    JAVA_HOME=/home/ochadoop/app/jdk

    HADOOP_HOME=/home/ochadoop/app/hadoop

    HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop

    SPARK_EXECUTOR_INSTANCES=50

    SPARK_EXECUTOR_CORES=2

    SPARK_EXECUTOR_MEMORY=4G

    SPARK_DRIVER_MEMORY=3G

    SPARK_YARN_APP_NAME="Spark-1.1.0"

    #export SPARK_YARN_QUEUE="default"

    SPARK_SUBMIT_LIBRARY_PATH=$SPARK_LIBRARY_PATH:$HADOOP_HOME/lib/native

    SPARK_JAVA_OPTS="-verbose:gc -XX:-UseGCOverheadLimit -XX: UseCompressedOops -XX:-PrintGCDetails -XX: PrintGCTimeStamps $SPARK_JAVA_OPTS -XX: HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/home/ochadoop/app/spark/`date %m%d%H%M%S`.hprof"

    export SPARK_HISTORY_OPTS="-Dspark.history.ui.port=18080 -Dspark.history.retainedApplications=1000 -Dspark.history.fs.logDirectory=hdfs://testcluster/eventLog"

spark-defaults.conf

    spark.serializer                    org.apache.spark.serializer.KryoSerializer

    spark.local.dir                     /data2/ochadoop/data/pseudo-dist/spark/local,/data3/ochadoop/data/pseudo-dist/spark/local

    spark.io.compression.codec          snappy

    spark.speculation                   false

    spark.yarn.executor.memoryOverhead  512

    #spark.storage.memoryFraction       0.4

    spark.eventLog.enabled              true

    spark.eventLog.dir                  hdfs://testcluster/eventLog

    spark.eventLog.compress             true

如下命令都是用root身份安装，或者在命令前加上sudo 采用yum安装方式安装 yum install mysql     #安装mysql客户端 yum install mysql-server  #安装mysql服务端 判断MySQL是否已经安装好： chkconfig --list|grep mysql 启动mysql服务： service mysqld start或者/etc/init.d/mysqld start 检查是否启动mysql服务： /etc/init.d/mysqld status 设置MySQL开机启动： chkconfig mysqld on  检查设置MySQL开机启动是否配置成功： chkconfig --list|grep mysql 显示2 3 4 5为on 创建root管理员 mysqladmin -uroot password root 登录 mysql -uroot -proot
