[Flink]flink1.13 on yarn的HA部署配置及测试

0.hadoop的hdfs和yarn高可用配置

参考我的另一篇博客：
https://blog.csdn.net/MyNameIsWangYi/article/details/124562376?spm=1001.2014.3001.5502

1.安装包准备（需要的可以联系我）

1.1 flink安装包

本文用的是：flink-1.13.6-bin-scala_2.11.tgz
https://archive.apache.org/dist/flink/

1.2 zookeeper和Hadoop的安装

apache-zookeeper-3.5.7-bin.tar.gz
hadoop-3.2.1.tar.gz

1.3 flink on yarn需要的hadoop包

flink-shaded-hadoop-3-uber-3.1.1.7.1.1.0-565-9.0.jar

2.解压并配置内容

2.1 /etc/profile配置

主要是后面的export内容

# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

pathmunge () {
    case ":${PATH}:" in
        *:"$1":*)
            ;;
        *)
            if [ "$2" = "after" ] ; then
                PATH=$PATH:$1
            else
                PATH=$1:$PATH
            fi
    esac
}


if [ -x /usr/bin/id ]; then
    if [ -z "$EUID" ]; then
        # ksh workaround
        EUID=`/usr/bin/id -u`
        UID=`/usr/bin/id -ru`
    fi
    USER="`/usr/bin/id -un`"
    LOGNAME=$USER
    MAIL="/var/spool/mail/$USER"
fi

# Path manipulation
if [ "$EUID" = "0" ]; then
    pathmunge /usr/sbin
    pathmunge /usr/local/sbin
else
    pathmunge /usr/local/sbin after
    pathmunge /usr/sbin after
fi

HOSTNAME=`/usr/bin/hostname 2>/dev/null`

if [ "$HISTCONTROL" = "ignorespace" ] ; then
    export HISTCONTROL=ignoreboth
else
    export HISTCONTROL=ignoredups
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL

# By default, we want umask to get set. This sets it for login shell
# Current threshold for system reserved uid/gids is 200
# You could check uidgid reservation validity in
# /usr/share/doc/setup-*/uidgid file
if [ $UID -gt 199 ] && [ "`/usr/bin/id -gn`" = "`/usr/bin/id -un`" ]; then
    umask 002
else
    umask 022
fi

for i in /etc/profile.d/*.sh /etc/profile.d/sh.local ; do
    if [ -r "$i" ]; then
        if [ "${-#*i}" != "$-" ]; then
            . "$i"
        else
            . "$i" >/dev/null
        fi
    fi
done

unset i
unset -f pathmunge

2.2 flink的配置

因为是yarn模式，无需配置master和worker，yarn会自行调度
/conf/flink-conf.yaml

3.启动

3.1 先启动yarn-session

./yarn-session.sh  -n 10  -tm 1024 -s 2 -nm bdp01 -d

3.2 flink的启动

分为两种：session 和 per-job，一般都用session模式

3.2.1 session方式启动demo

注：必须在active状态下的namenode上进行

./bin/flink run examples/batch/WordCount.jar

3.2.2 per-job方式启动demo

./bin/flink run -m yarn-cluster ./examples/batch/WordCount.jar

3.2.3 flink启动参数说明

1 参数必选 ： 
     -n,--container    分配多少个yarn容器 (=taskmanager的数量)  
2 参数可选 ： 
     -D                         动态属性  
     -d,--detached                   独立运行  
     -jm,--jobManagerMemory     JobManager的内存 [in MB]  
     -nm,--name                      在YARN上为一个自定义的应用设置一个名字  
     -q,--query                      显示yarn中可用的资源 (内存, cpu核数)  
     -qu,--queue                指定YARN队列.  
     -s,--slots                 每个TaskManager使用的slots数量  
     -tm,--taskManagerMemory    每个TaskManager的内存 [in MB]  
     -z,--zookeeperNamespace    针对HA模式在zookeeper上创建NameSpace 
     -id,--applicationId  YARN集群上的任务id，附着到一个后台运行的yarn session中
 
3 run [OPTIONS]    
 
    run操作参数:  
    -c,--class   如果没有在jar包中指定入口类，则需要在这里通过这个参数指定  
    -m,--jobmanager   指定需要连接的jobmanager(主节点)地址，使用这个参数可以指定一个不同于配置文件中的jobmanager  
    -p,--parallelism    指定程序的并行度。可以覆盖配置文件中的默认值。
 
4 启动一个新的yarn-session,它们都有一个y或者yarn的前缀
 
    例如：./bin/flink run -m yarn-cluster -yn 2 ./examples/batch/WordCount.jar 
    
    连接指定host和port的jobmanager：
    ./bin/flink run -m SparkMaster:1234 ./examples/batch/WordCount.jar -input hdfs://hostname:port/hello.txt -output hdfs://hostname:port/result1
 
    启动一个新的yarn-session：
    ./bin/flink run -m yarn-cluster -yn 2 ./examples/batch/WordCount.jar -input hdfs://hostname:port/hello.txt -output hdfs://hostname:port/result1
 
5 注意：命令行的选项也可以使用./bin/flink 工具获得。
 
6 Action "run" compiles and runs a program.
    
      Syntax: run [OPTIONS]  
      "run" action options:
         -c,--class                Class with the program entry point
                                              ("main" method or "getPlan()" method.
                                              Only needed if the JAR file does not
                                              specify the class in its manifest.
         -C,--classpath                  Adds a URL to each user code
                                              classloader  on all nodes in the
                                              cluster. The paths must specify a
                                              protocol (e.g. file://) and be
                                              accessible on all nodes (e.g. by means
                                              of a NFS share). You can use this
                                              option multiple times for specifying
                                              more than one URL. The protocol must
                                              be supported by the {@link
                                              java.net.URLClassLoader}.
         -d,--detached                        If present, runs the job in detached

         -n,--allowNonRestoredState           Allow to skip savepoint state that
                                              cannot be restored. You need to allow
                                              this if you removed an operator from
                                              your program that was part of the
                                              program when the savepoint was
                                              triggered.
         -p,--parallelism        The parallelism with which to run the
                                              program. Optional flag to override the
                                              default value specified in the
                                              configuration.
         -q,--sysoutLogging                   If present, suppress logging output to
                                              standard out.
         -s,--fromSavepoint    Path to a savepoint to restore the job
                                              from (for example
                                              hdfs:///flink/savepoint-1537).
 
7  Options for yarn-cluster mode:
         -d,--detached                        If present, runs the job in detached
                                              mode
         -m,--jobmanager                 Address of the JobManager (master) to
                                              which to connect. Use this flag to
                                              connect to a different JobManager than
                                              the one specified in the
                                              configuration.

         -yd,--yarndetached                   If present, runs the job in detached
                                              mode (deprecated; use non-YARN
                                              specific option instead)

         -ynm,--yarnname                 Set a custom name for the application
                                              on YARN
         -yq,--yarnquery                      Display available YARN resources
