Flink On Yarn 模式部署提交

一、环境准备

Ubuntu

hadoop 2.6.0（官网下载）

Flink 1.12.2

jdk 8

二、Hadoop 完全分布式-yarn配置

  1. 永久关闭防火墙

  2. 修改主机名

    vim /etc/hosts

    192.168.73.130 hadoop01

  3. 修改环境变量

    export JAVA_HOME=/usr/lib/jdk export HADOOP_HOME=/home/ad/hadoop-2.6.0 export HADOOP_PREFIX=HADOOP_HOME export FLINK_HOME=/usr/lib/flink export HADOOP_CLASSPATH=`{HADOOP_HOME}/bin/hadoop classpath` export PATH=PATH:JAVA_HOME/bin:HADOOP_HOME/bin:HADOOP_HOME/sbin:$FLINK_HOME/bin

    环境变量生效

    $ source /etc/profile

    验证

    $ hadoop version

    Hadoop 2.6.0 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r e3496499ecb8d220fba99dc5ed4c99c8f9e33bb1 Compiled by jenkins on 2014-11-13T21:10Z Compiled with protoc 2.5.0 From source with checksum 18e43357c8f927c0695f1e9522859d6a This command was run using /home/ad/hadoop-2.6.0/share/hadoop/common/hadoop-common-2.6.0.jar

  4. SSH免密登录

  5. 修改配置文件

core-site.xml

<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://hadoop01:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/opt/hadoop/tmp</value>
</property>
</configuration>

hadoop-env.sh mapred-env.sh yarn-env.sh

修改$JAVA_HOME 路径

hdfs-site.xml

<configuration>
<property>

<name>dfs.replication</name>
<value>1</value> </property>
</configuration>

yarn-site.xml

<configuration>


<property>

<name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>hadoop01</value>
</property>
</configuration>

cp mapred-site.xml.templat mapred-site.xml

<configuration>

<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>

slaves

hadoop01

  1. hadoop01上格式化

hadoop namenode -format

  1. 启动hadoop集群

$ start-all.sh

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh Starting namenodes on [hadoop01] hadoop01: starting namenode, logging to /home/ad/hadoop-2.6.0/logs/hadoop-root-namenode-ad-virtual-machine.out hadoop01: starting datanode, logging to /home/ad/hadoop-2.6.0/logs/hadoop-root-datanode-ad-virtual-machine.out Starting secondary namenodes [0.0.0.0] 0.0.0.0: starting secondarynamenode, logging to /home/ad/hadoop-2.6.0/logs/hadoop-root-secondarynamenode-ad-virtual-machine.out starting yarn daemons starting resourcemanager, logging to /home/ad/hadoop-2.6.0/logs/yarn-root-resourcemanager-ad-virtual-machine.out hadoop01: starting nodemanager, logging to /home/ad/hadoop-2.6.0/logs/yarn-root-nodemanager-ad-virtual-machine.out

  1. 访问hadoop01:8080

三、验证hadoop yarn

创建HDFS数据目录

创建一个目录，用于保存MapReduce任务的输入文件：
hadoop fs -mkdir -p /data/wordcount1

创建一个目录，用于保存MapReduce任务的输出文件：

hadoop fs -mkdir /output1

查看刚刚创建的两个目录：

hadoop fs -ls /
drwxr-xr-x - root supergroup 0 2017-09-01 20:34 /data
drwxr-xr-x - root supergroup 0 2017-09-01 20:35 /output1

（3）创建一个单词文件，并上传到HDFS

创建的单词文件如下：

cat myword.txt
leaf yyh
yyh xpleaf
katy ling
yeyonghao leaf
xpleaf katy1.2.3.4.5.6.</pre>

上传该文件到HDFS中：

hadoop fs -put myword.txt /data/wordcount1

在HDFS中查看刚刚上传的文件及内容：

hadoop fs -ls /data/wordcount
-rw-r--r-- 1 root supergroup 57 2017-09-01 20:40 /data/wordcount/myword.txt
hadoop fs -cat /data/wordcount/myword.txt
leaf yyh
yyh xpleaf
katy ling
yeyonghao leaf
xpleaf katy1.2.3.4.5.6.7.8.</pre>

（4）运行wordcount程序

执行如下命令：

登录后复制

hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.5.jar wordcount /data/wordcount /output/wordcount

三、Flink on yarn环境搭建

  1. Flink Session

    略

  2. Flink Per-job
