一:下载Flink,并制作parcel包
1.相关资源下载
1.1) flink下载地址: https://archive.apache.org/dist/flink/flink-1.17.0/flink-1.17.0-bin-scala_2.12.tgz
1.2) parcel制作工具:https://github.com/pkeropen/flink-parcel.git
1.3) cm验证工具:https://github.com/cloudera/cm_ext.git
说明: 需要用到maven,unzip,确保已安装并配置mvn环境变量,需要提前下载上面的两个工具和flink.到本地,然后上传到服务器。
红框里面的是下载下来,重命名,解压放到 flink-parcel目录里面的。黄框里的是后面制作是生成的。下载好的包放入flink-parcel目录里面需要将名字和图片一致。
用到的命令:
mvn -version #验证本地maven安装环境变量配置是否OK.
unzip flink-parcel-master.zip # 解压包到当前目录
mv ./flink-parcel-master/* ./ flink-parcel #重命名
chmod +x ./build.sh #将build.sh 文件赋予可执行
unzip ./cm_ext-master.zip #解压包到当前目录
mv ./cm_ext-master ./cm_ext #重命名
mv ./cm_ext /opt/install/flink-parcel/ #移动到flink-parcel目录下
mv ./flink-1.17.0-bin-scala_2.12.tgz /opt/install/flink-parcel/ #移动到flink-parcel目录下
2. 修改配置
修改flink-parcel.properties为以下内容:
#FLINK 下载地址 此地址写上只是为了脚本取值时有值可取,是否正确无所谓,因为目录里面已经包含了下载好的包,会用下载好的包。此行注释掉,后面脚本运行会报错。
FLINK_URL=https://mirrors.tuna.tsinghua.edu.cn/apache/flink/flink-1.17.0/flink-1.17.0-bin-scala_2.12.tgz#flink版本号
FLINK_VERSION=1.17.0
#扩展版本号
EXTENS_VERSION=BIN-SCALA_2.12
#操作系统版本,以centos为例
OS_VERSION=7
#CDH 小版本
CDH_MIN_FULL=5.2
CDH_MAX_FULL=6.3.3
#CDH大版本
CDH_MIN=5
CDH_MAX=6
准备工作一:
执行脚本时会有一个报错,已查阅
/opt/cloudera/parcels/FLINK/lib/flink/bin/flink-yarn.sh: line 17: rotateLogFilesWithPrefix: command not found
此脚本里面缺少俩个方法,添加上。
参考:flink/config.sh at release-1.11.6 · apache/flink · GitHub
# Auxilliary functions for log file rotation
rotateLogFilesWithPrefix() {
dir=$1
prefix=$2
while read -r log ; do
rotateLogFile "$log"
# find distinct set of log file names, ignoring the rotation number (trailing dot and digit)
done < <(find "$dir" ! -type d -path "${prefix}*" | sed s/\.[0-9][0-9]*$// | sort | uniq)
}
rotateLogFile() {
log=$1;
num=$MAX_LOG_FILE_NUMBER
if [ -f "$log" -a "$num" -gt 0 ]; then
while [ $num -gt 1 ]; do
prev=`expr $num - 1`
[ -f "$log.$prev" ] && mv "$log.$prev" "$log.$num"
num=$prev
done
mv "$log" "$log.$num";
fi
}
将上述俩个方法加到/opt/cloudera/parcels/FLINK/lib/flink/bin/flink-yarn.sh 脚本里面,加到readMasters() 这个方法上面。其实加到哪个方法前应该都可以,看上面官方,这俩个方法是在这个方法上面,所以不乱自操作。加入后,俩个方法和上面官方可以对比下代码,看是否有偏差。
准备工作二:
在安装flink的机器上环境变量加上 vim /etc/profile
export HADOOP_CLASSPATH=`hadoop classpath`
source /etc/profile #使生效
echo ${HADOOP_CLASSPATH} #验证
3. 开始build
cd /opt/install/flink-parcel
./build.sh parcel
#maven会下载很多依赖,打包完成后会在当前目录生成FLINK-1.17.0-BIN-SCALA_2.11_build文件里面就包含了三个文件:
FLINK-1.17.0-BIN-SCALA_2.12-el7.parcel
FLINK-1.17.0-BIN-SCALA_2.12-el7.parcel.sha
manifest.json
构建flink-yarn csd包
./build.sh csd_on_yarn
执行完回生成FLINK_ON_YARN-1.17.0.jar文件
好了,制作完成了,下面就是加入到CDH里面。(我是在cdh03上做的,但是/opt/cloudera/parcel-repo 这个目录只在cdh01上有,scp拷贝到01上的)
(1)将FLINK-1.17.0-BIN-SCALA_2.11_build里的文件放到/opt/cloudera/parcel-repo,并修改所属用户和组
(2)将FLINK_ON_YARN-1.17.0.jar 放到 /opt/cloudera/csd/,并修改所属用户和组
cd /opt/cloudera/parcel-repo
mv manifest.json manifest.json.bak #先将已有的备份
cp /opt/install/flink-parcel/FLINK-1.17.0-BIN-SCALA_2.12_build/* ./
chown cloudera-scm. ./*
cp /opt/install/flink-parcel/FLINK_ON_YARN-1.17.0.jar /opt/cloudera/csd/
cd /opt/cloudera/csd/
chown cloudera-scm. FLINK_ON_YARN-1.17.0.jar
二:开始在CDH页面分发激活
点击Parcel,然后右上角点击 检查新Parcel.
按照提示,会进行分配,然后点击激活就可以
三:CDH添加Flink-yarn 服务
主页点击添加服务。如果这时候点击过去没有看到 flink-yarn 的服务,需要将CDH重启,此时我的就是没有,先是在CDH的主节点重启 systemctl stop cloudera-scm-server。发现停不掉。就直接整个大重启了,因为是新搭建好的,还没有放入数据和任务。所以就直接全部重启了。先在CDH页面上停掉了Cloudera Management Service 服务,然后又把集群所有的服务都停掉了,然后每台机器的cloudera-scm-server、cloudera-scm-agent也都停掉了,重启按照反的顺序重启。然后就可以看到有flink-yarn服务了。
选择部署的主机,然后进入配置页面。下面俩项不予配置,不给验证。点击继续。启动。
四:启动不起来的问题解决
启动时会提示一个 HBASE_CONF_DIR 没有设置。这时候关闭本页面,直接进入CDH主页,点击flin-yarn组件,进入,点击配置 输入 Flink-yarn 服务环境高级配置代码段(安全阀)添加如下:
HADOOP_USER_NAME=flink
HADOOP_CONF_DIR=/etc/hadoop/conf
HADOOP_HOME=/opt/cloudera/parcels/CDH
HADOOP_CLASSPATH=/opt/cloudera/parcels/CDH/jars/*
HBASE_CONF_DIR=/etc/hbase/conf
这时不报这个错误了,但是还报了个其他的错误,找不到具体的报错信息了。
解决是将 flink-shaded-hadoop-3-uber-3.1.1.7.2.9.0-173-9.0.jar 放到了 /opt/cloudera/parcels/FLINK/lib/flink/lib 目录下。https://mvnrepository.com/artifact/org.apache.flink/flink-shaded-hadoop-3-uber
中间还遇到端口被占,改了rest.port 端口 8082。并且在服务器上 /opt/cloudera/parcels/FLINK/lib/flink/conf master也改了 localhost:8082。
Flink启动时报错:NoSuchMethodError: org.apache.commons.cli.Option.builder
【问题与解决】Flink启动时报错:NoSuchMethodError: org.apache.commons.cli.Option.builder_flink程序报错nosuchfielderror: runtime_mode_MomentNi的博客-CSDN博客
并且还有个启动报错,然后我这个flink服务安装到了有 JobHistoryServer 的服务的节点上。是后来将之前的flink-yarn换了节点部署。直接从节点上删除了然后重新添加的角色实例。
这时才遇到了版本的错误:
flink的启动日志在:/var/log/flink/flink-yarn.out 里面。下面是全部的报错日志。也怀疑过其他问题,但是最让我先想到的应该是zk版本不兼容。本来想的是直接在flink配置上去掉zk.但是提示,必须要勾选ZK.后面准备集成高版本zk到集群然后配置flink,看是否有其他问题。

后来换高版本的切换不上去,还用自带的zookeeper启动起来了,只是一会,立刻就会失败,在yarn上看到了任务直接是失败了,查看日志如下:
然后在flink配置里面添加
重启启动再次尝试 ,报错有变化:

然后查看启动时设置的大小,
修改配置文件应该也可以,但是机器是有内存的,直接修改CDH上的配置,给加大。
默认是1G,调到4G,然后启动成功。
六:重新适配Flink服务
将之前已有的flink角色实例,删掉,重新添加,准备换zk。
后来不管怎么配置,这里始终都只能选择这一个,没有第二个可以选择。并且在配置文件里面配置后来添加进来的zk角色列表,都会在启动flink服务时,被覆盖掉。在哪里修改都不好使。并且想了下,其实很简单的,只需要一个flink包就可以 flink on yarn 执行,在cdh上集成后,开启集群,flink在提交on yarn 任务时,会冲突,并没有什么实际意义。故放弃在CDH上集成高版本flink。可以尝试直接升级CDH自带的ZK版本,这样应该是可以适配flink高版本的。 但又有可能会对其他组件有兼容性问题,还是谨慎尝试。文章来源:https://www.toymoban.com/news/detail-798200.html
