篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了spark 2.0.0集群安装与hive on spark配置相关的知识，希望对你有一定的参考价值。
1. 环境准备:
JDK1.8
hive 2.3.4
hadoop 2.7.3
hbase 1.3.3
scala 2.11.12
mysql5.7
2. 下载spark2.0.0
cd /home/worksapce/software wget https://archive.apache.org/dist/spark/spark-2.0.0/spark-2.0.0-bin-hadoop2.7.tgz tar -xzvf spark-2.0.0-bin-hadoop2.7.tgz mv spark-2.0.0-bin-hadoop2.7 spark-2.0.0
3. 配置系统环境变量
vim /etc/profile
末尾添加
#spark export SPARK_HOME=/home/workspace/software/spark-2.0.0 export PATH=:$PATH:$SPARK_HOME/bin
4. 配置spark-env.sh
cd /home/workspace/software/spark-2.0.0/conf cp spark-env.sh.template spark-env.sh vim spark-env.sh
末尾添加:
export JAVA_HOME=/usr/java/jdk1.8.0_172-amd64 export SCALA_HOME=/home/workspace/software/scala-2.11.12 export HADOOP_HOME=/home/workspace/hadoop-2.7.3 export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop export SPARK_HOME=/home/workspace/software/spark-2.0.0 export SPARK_DIST_CLASSPATH=$(/home/workspace/hadoop-2.7.3/bin/hadoop classpath) export SPARK_LIBRARY_PATH=$SPARK_HOME/lib export SPARK_LAUNCH_WITH_SCALA=0 export SPARK_WORKER_DIR=$SPARK_HOME/work export SPARK_LOG_DIR=$SPARK_HOME/logs export SPARK_PID_DIR=$SPARK_HOME/run export SPARK_MASTER_IP=192.168.1.101 export SPARK_MASTER_HOST=192.168.1.101 export SPARK_MASTER_WEBUI_PORT=18080 export SPARK_MASTER_PORT=7077 export SPARK_LOCAL_IP=192.168.1.101 export SPARK_WORKER_CORES=4 export SPARK_WORKER_PORT=7078 export SPARK_WORKER_MEMORY=4g export SPARK_DRIVER_MEMORY=4g export SPARK_EXECUTOR_MEMORY=4g
5. 配置spark-defaults.conf
cd /home/workspace/software/spark-2.0.0/conf cp spark-defaults.conf.template spark-defaults.conf vim spark-defaults.conf
末尾添加
spark.master spark://192.168.1.101:7077 spark.eventLog.enabled true spark.eventLog.dir hdfs://192.168.1.101:9000/spark-log spark.serializer org.apache.spark.serializer.KryoSerializer spark.executor.memory 4g spark.driver.memory 4g spark.executor.extraJavaOptions -XX:+PrintGCDetails -Dkey=value -Dnumbers="one two three"
6. 配置slaves
cd /home/workspace/software/spark-2.0.0/conf cp slaves.template slaves vim slaves
末尾添加
192.168.1.101 192.168.1.102 192.168.1.103
7. 创建相关目录（在spark-env.sh中定义)
hdfs dfs -mkdir -p /spark-log hdfs dfs -chmod 777 /spark-log mkdir -p $SPARK_HOME/work $SPARK_HOME/logs $SPARK_HOME/run
mkdir -p $HIVE_HOME/logs
8.修改hive-site.xml
vim $HIVE_HOME/conf/hive-site.xml
把文件内容修改为
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>hive.metastore.schema.verification</name> <value>false</value> </property> <property> <name>hive.metastore.warehouse.dir</name> <value>/hive/warehouse</value> <description>location of default database for the warehouse</description> </property> <property> <name>hive.exec.scratchdir</name> <value>/hive/tmp</value> <description>Scratch space for Hive jobs</description> </property> <property> <name>hive.querylog.location</name> <value>/hive/log</value> </property> <property> <name>hive.metastore.uris</name> <value>thrift://192.168.1.103:9083</value> </property> <!--hive server2 settings--> <property> <name>hive.server2.thrift.bind.host</name> <value>192.168.1.103</value> </property> <property> <name>hive.server2.thrift.port</name> <value>10000</value> </property> <property> <name>hive.server2.webui.host</name> <value>192.168.1.103</value> </property> <property> <name>hive.server2.webui.host.port</name> <value>10002</value> </property> <property> <name>hive.server2.long.polling.timeout</name> <value>5000</value> </property> <property> <name>hive.server2.enable.doAs</name> <value>true</value> </property> <!--metadata database connection string settings--> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://192.168.1.103:3308/hive?createDatabaseIfNotExist=true</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hive</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>hive</value> </property> <property> <name>datanucleus.autoCreateSchema </name> <value>false</value> <description>creates necessary schema on a startup if one doesn‘t exist. set this to false, after creating it once</description> </property> <property> <name>datanucleus.fixedDatastore</name> <value>true</value> </property> <!-- hive on mr--> <!-- <property> <name>mapred.job.tracker</name> <value>http://192.168.1.101:9001</value> </property> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> --> <!--hive on spark or spark on yarn --> <property> <name>hive.execution.engine</name> <value>spark</value> </property> <property> <name>spark.home</name> <value>/home/workspace/software/spark-2.0.0</value> </property> <property> <name>spark.master</name> <value>spark://192.168.1.101:7077</value> <!-- 或者yarn-cluster/yarn-client --> </property> <property> <name>spark.submit.deployMode</name> <value>client</value> </property> <property> <name>spark.eventLog.enabled</name> <value>true</value> </property> <property> <name>spark.eventLog.dir</name> <value>hdfs://192.168.1.101:9000/spark-log</value> </property> <property> <name>spark.serializer</name> <value>org.apache.spark.serializer.KryoSerializer</value> </property> <property> <name>spark.executor.memeory</name> <value>4g</value> </property> <property> <name>spark.driver.memeory</name> <value>4g</value> </property> <property> <name>spark.executor.extraJavaOptions</name> <value>-XX:+PrintGCDetails -Dkey=value -Dnumbers="one two three"</value> </property> <!--concurrency support--> <property> <name>hive.support.concurrency</name> <value>true</value> <description>Whether hive supports concurrency or not.

9. 拷贝hive-site.xml到spark/conf下
cp $HIVE_HOME/conf/hive-site.xml $SPARK_HOME/conf
10 分发到192.168.1.102，192.168.1.103
cd /home/workspace/software/ scp -r spark-2.0.0 192.168.1.102:/home/workspace/software scp -r spark-2.0.0 192.168.1.103:/home/workspace/software
修改102，103上的SPARK_LOCAL_IP值
vim /home/workspace/software/spark-2.0.0/conf/spark-env.sh
将SPARK_LOCAL_IP分别改为192.168.1.102，192.168.1.103
11 将mysql jar包复制到$SPARK_HOME/lib目录下（每台机器都要做)
cp $HIVE_HOME/lib/mysql-connector-java-5.1.47.jar $SPARK_HOME/lib
注：本例中之前已经安装好hive，如果没有，请到mysql官网网站下载对应的jdbc jar包
12. 启动spark集群
在spark master节点上（本例为192.168.1.101)执行下面语句
$SPARK_HOME/sbin/start-all.sh
192.168.1.101
192.168.1.102:
192.168.1.103:
浏览器打开http:192.168.1.101:18080
13.测试使用

13 FAQ:
13.1 如果在使用过程中遇到类似下面的错误
Exception in thread "main" java.lang.NoSuchFieldError: SPARK_RPC_SERVER_ADDRESS
通过查看hive的日志文件（在/tmp/{user}/hive.log),这是因为默认使用的spark安装包是继承了hive的包，名字为spark-xxx-bin-hadoopxx.xx.tgz都是继承了hive的包，在hive on spark模式下，会出现冲突，解决办法有两个：
1） 手动编译spark不包含hive的包，具体请参见本人的博文Spark2.0.0源码编译,编译指令为：
./make-distribution.sh --name "hadoop2.7.3-without-hive" --tgz -Dhadoop.version=2.7.3 -Dscala-2.11 -Phadoop-2.7 -Pyarn -DskipTests clean package
用编译出来的包来安装。
2） 删除预编译包中hive的jar包，具体操作为：
cd $SPARK_HOME/jars rm -f hive-* rm -rf spark-hive_* #删除下面6个文件 # hive-beeline-1.2.1.spark2.jar # hive-cli-1.2.1.spark2.jar # hive-exec-1.2.1.spark2.jar # hive-jdbc-1.2.1.spark2.jar # hive-metastore-1.2.1.spark2.jar # spark-hive_2.11-2.0.0.jar # spark-hive-thriftserver_2.11-2.0.0.jar
注意：每台机器都要做.
13.2 如果出现类似下面的错误

这是因为hive无法加载spark的jar包，解决办法为：
$HIVE_HOME/bin/hive
在执行hive之前添加下面的语句，把spark的jar包添加到hive的class path中
SPARK_HOME=/home/workspace/software/spark-2.0.0 for f in ${SPARK_HOME}/jars/*.jar; do CLASSPATH=${CLASSPATH}:$f; done
本人添加的位置为：
或者直接把$SPARK_HOME/jars/spark*复制到$HIVE_HOME/lib下，
cp $SPARK_HOME/jars/spark* $HIVE_HOME/lib
个人感觉修改hive启动脚本更好一些。
