在standalone模式下运行yarn 0.9.0对HDFS上的数据进行计算

1.通读http://spark.incubator.apache.org/docs/latest/spark-standalone.html

2.在每台机器上将spark安装到/opt/spark

3.在第一台机器上启动spark master.

[root@jfp3-1 latest]# ./sbin/start-master.sh

在logs目录查看日志:

[root@jfp3-1 latest]# tail -100f logs/spark-root-org.apache.spark.deploy.master.Master-1-jfp3-1.out
Spark Command: /usr/java/default/bin/java -cp :/opt/spark/spark-0.9.0-incubating-bin-hadoop2/conf:/opt/spark/spark-0.9.0-incubating-bin-hadoop2/assembly/target/scala-2.10/spark-assembly_2.10-0.9.0-incubating-hadoop2.2.0.jar -Dspark.akka.logLifecycleEvents=true -Djava.library.path= -Xms512m -Xmx512m org.apache.spark.deploy.master.Master --ip jfp3-1 --port 7077 --webui-port 8080

启动http://jfp3-1:8080上看集群的状况

4.在第2，3，4太机器上启动spark worker

[root@jfp3-2 latest]# ./bin/spark-class org.apache.spark.deploy.worker.Worker spark://192.168.0.71:7077
log4j:WARN No appenders could be found for logger (akka.event.slf4j.Slf4jLogger).

14/02/21 05:06:10 ERROR Worker: All masters are unresponsive! Giving up.

同时在master的日志中也发现错误日志:

14/02/21 05:06:23 ERROR EndpointWriter: AssociationError [akka.tcp://sparkMaster@jfp3-1:7077] -> [akka.tcp://sparkWorker@jfp3-3:53721]: Error [Association failed with [akka.tcp://sparkWorker@jfp3-3:53721]] [

]

用IP连spark master出现问题改用hostname：

[root@jfp3-2 latest]# ./bin/spark-class org.apache.spark.deploy.worker.Worker spark://jfp3-1:7077
log4j:WARN No appenders could be found for logger (akka.event.slf4j.Slf4jLogger).

14/02/21 05:08:41 INFO Worker: Successfully registered with master spark://jfp3-1:7077

5.在spark master界面上查看集群状态，发现多了3个worker

6. 启动HDFS集群

7.进入spark-shell界面：

[root@jfp3-1 latest]# MASTER=spark://jfp3-1:7077 ./bin/spark-shell

计算HDFS上的一个文件包含2144这个字符的行数
