flink集群地址

• ddcve: master
• dddve: slave
• ddeve: slave

解壓

tar -xzvf flink-1.6.1-bin-hadoop28-scala_2.11.tgz
mv flink-1.6.1 flink
cd flink

修改配置

• 指定master
  • vim conf/flink-conf.yaml

  jobmanager.rpc.address: ddcve   # 指定master
   
  

• 指定slaves

echo -e "dddve\nddeve" > conf/slaves

添加yarn配置項

• hadoop/etc/hadoop/yarn-site.xml

<property>
    <name>yarn.nodemanager.resource.cpu-vcores</name>
    <value>8</value>
</property>

啟動flink

./bin/start-cluster.sh

• 輸出結果如下

Starting HA cluster with 2 masters.
Starting standalonesession daemon on host ddcvc.
Starting standalonesession daemon on host ddcve.
Starting taskexecutor daemon on host dddve.
Starting taskexecutor daemon on host ddeve.
 

flink on yarn

以下操作都在slave

• 啟動yarn-session

./bin/yarn-session.sh -d -n 4 -tm 2048 -s 4

• 提交job

# 先在hdfs創建輸入文件
hadoop fs -copyFromLocal /tmp/passwd /tmp/passwd

# 提交
./bin/flink run ./examples/batch/WordCount.jar --input hdfs:///tmp/passwd

flink with zookeeper

• 修改conf/flink-conf.yaml

high-availability: zookeeper
high-availability.storageDir: hdfs:///flink/ha/
high-availability.zookeeper.quorum: ddcva:2181,dddva:2181,ddeva:2181
recovery.zookeeper.path.root: /flink
high-availability.zookeeper.client.acl: open
state.backend: filesystem
 

• 修改conf/masters

ddcvc:8081
ddcve:8081
