环境篇:Atlas2.0.0兼容CDH6.2.0部署

Atlas 是什么?

Atlas是一组可扩展和可扩展的核心基础治理服务,使企业能够有效地满足Hadoop中的合规性要求,并允许与整个企业数据生态系统集成。

Apache Atlas为组织提供了开放的元数据管理和治理功能,以建立其数据资产的目录,对这些资产进行分类和治理,并为数据科学家,分析师和数据治理团队提供围绕这些数据资产的协作功能。

如果没有Atlas

大数据表依赖问题不好解决,元数据管理需要自行开发,如:hive血缘依赖图

对于表依赖问题,没有一个可以查询的工具,不方便错误定位,即业务sql开发

  • 字段与字段之间的血缘依赖

1 Atlas 架构原理

2 Atlas 安装及使用

安装需要组件,HDFS、Yarn、Zookeeper、Kafka、Hbase、Solr、Hive,Python2.7环境

需要Maven3.5.0以上,jdk_151以上,python2.7。

2.1 下载源码包2.0.0,IDEA打开

2.2 修改相关版本与CDH版本对应

<hadoop.version>3.0.0</hadoop.version>
<hbase.version>2.1.0</hbase.version>
<kafka.version>2.1.0</kafka.version>
<zookeeper.version>3.4.5</zookeeper.version>

2.3 修改配置文件

apache-atlas-2.0.0-sources\apache-atlas-sources-2.0.0\distro\src\conf\atlas-application.properties

#集成修改kafka配置
atlas.notification.embedded=false		    #false外置的kafka

atlas.kafka.zookeeper.session.timeout.ms=60000
atlas.kafka.zookeeper.connection.timeout.ms=30000
atlas.kafka.enable.auto.commit=true
#集成修改其他配置
atlas.rest.address=http://cdh01.cm:21000	#访问地址端口,此值修改不生效,默认本地21000端口,此端口和impala冲突
atlas.server.run.setup.on.start=false		   #如果启用并设置为true,则在服务器启动时将运行安装步骤
atlas.audit.hbase.zookeeper.quorum=cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181
#集成添加hive钩子配置(文件最下面即可)
#在hive中做任何操作,都会被钩子所感应到,并生成相应的事件发往atlas所订阅的kafka-topic,再由atlas进行元数据生成和存储管理

    #开启或关闭三种验证方法

#export MANAGE_LOCAL_HBASE=false  (false外置的zk和hbase)

        <level value="debug" />
        <appender-ref ref="perf_appender" />
    </logger>

2.4 编译打包

export MAVEN_OPTS="-Xms2g -Xmx2g"
mvn clean -DskipTests install
mvn clean -DskipTests package -Pdist

出现错误,使用-X参数打印详情对应解决,无非是一些网络,node代理等

Build将创建以下文件,这些文件用于安装Apache Atlas。

2.5 创建安装目录,上传安装包

mkdir /usr/local/src/atlas
cd /usr/local/src/atlas
#复制apache-atlas-2.0.0-bin.tar.gz到安装目录
tar -zxvf apache-atlas-2.0.0-bin.tar.gz
cd apache-atlas-2.0.0/conf

2.5.1 集成Hbase

  • 添加hbase集群配置文件到apache-atlas-2.0.0/conf/hbase下(这里连接的路径需要和上面配置中一样)
ln -s /etc/hbase/conf/ /usr/local/src/atlas/apache-atlas-2.0.0/conf/hbase/
#ln -s /opt/cloudera/parcels/CDH-6.2.0-1.cdh6.2.0.p0.967373/lib/hbase/conf/ /usr/local/src/atlas/apache-atlas-2.0.0/conf/hbase/

2.5.2 安装集成Solr

http://archive.apache.org/dist/lucene/solr/7.5.0/

官网推荐的solr节点数为3,内存为32G

  • 所有节点
mkdir /usr/local/src/solr
cd /usr/local/src/solr
  • 主节点上传包
tar -zxvf solr-7.5.0.tgz
cd solr-7.5.0/
  • 主节点修改 vim /usr/local/src/solr/solr-7.5.0/bin/solr.in.sh

ZK_HOST="cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181"

SOLR_HOST="cdh01.cm"

SOLR_PORT=8983

  • 主节点分发
scp -r /usr/local/src/solr/solr-7.5.0 root@cdh02.cm:/usr/local/src/solr
scp -r /usr/local/src/solr/solr-7.5.0 root@cdh03.cm:/usr/local/src/solr

分发完,将SOLR_HOST改为对应机器

  • 集成solr

将apache-atlas-2.0.0/conf/solr文件拷贝到/usr/local/src/solr/solr-7.5.0/,更名为atlas-solr

scp -r /usr/local/src/atlas/apache-atlas-2.0.0/conf/solr/ root@cdh01.cm:/usr/local/src/solr/solr-7.5.0/
scp -r /usr/local/src/atlas/apache-atlas-2.0.0/conf/solr/ root@cdh02.cm:/usr/local/src/solr/solr-7.5.0/
scp -r /usr/local/src/atlas/apache-atlas-2.0.0/conf/solr/ root@cdh03.cm:/usr/local/src/solr/solr-7.5.0/
  • 所有solr节点操作并启动
cd /usr/local/src/solr/solr-7.5.0/
mv solr/ atlas-solr
#所有节点创建用户附权限    
useradd atlas && echo atlas | passwd --stdin atlas
chown -R atlas:atlas /usr/local/src/solr/
#所有节点执行启动(cloud模式)   
su atlas
/usr/local/src/solr/solr-7.5.0/bin/solr start -c -z cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181 -p 8983

  • 随便solr节点创建collection
/usr/local/src/solr/solr-7.5.0/bin/solr create -c  vertex_index -d /usr/local/src/solr/solr-7.5.0/atlas-solr -shards 3 -replicationFactor 2

/usr/local/src/solr/solr-7.5.0/bin/solr create -c  edge_index -d /usr/local/src/solr/solr-7.5.0/atlas-solr -shards 3 -replicationFactor 2
    
/usr/local/src/solr/solr-7.5.0/bin/solr create -c  fulltext_index -d /usr/local/src/solr/solr-7.5.0/atlas-solr -shards 3 -replicationFactor 2
   
#如果创建错误,可使用 /opt/cloudera/parcels/CDH/lib/solr/bin/solr delete -c ${collection_name} 删除
#切换root用户继续配置其他
su root

2.5.3 集成kafka

  • 创建kafka-topic
kafka-topics --zookeeper cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181 --create --replication-factor 3 --partitions 3 --topic _HOATLASOK
kafka-topics --zookeeper cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181 --create --replication-factor 3 --partitions 3 --topic ATLAS_ENTITIES
kafka-topics --zookeeper cdh01.cm:2181,cdh02.cm:2181,cdh03.cm:2181 --create --replication-factor 3 --partitions 3 --topic ATLAS_HOOK

2.5.5 集成Hive

  • 将 atlas-application.properties 配置文件,压缩加入到 atlas-plugin-classloader-2.0.0.jar 中
#必须在此路径打包,才能打到第一级目录下
cd /usr/local/src/atlas/apache-atlas-2.0.0/conf

zip -u /usr/local/src/atlas/apache-atlas-2.0.0/hook/hive/atlas-plugin-classloader-2.0.0.jar atlas-application.properties
  • 修改 hive-site.xml

<property>
    <name>hive.exec.post.hooks</name>
    <value>org.apache.atlas.hive.hook.HiveHook</value>
</property>
  • 修改 hive-env.sh 的 Gateway 客户端环境高级配置代码段(安全阀)

HIVE_AUX_JARS_PATH=/usr/local/src/atlas/apache-atlas-2.0.0/hook/hive
  • 修改 HIVE_AUX_JARS_PATH

  • 修改 hive-site.xml 的 HiveServer2 高级配置代码段(安全阀)

<property>
    <name>hive.exec.post.hooks</name>
    <value>org.apache.atlas.hive.hook.HiveHook</value>
</property>
<property>
    <name>hive.reloadable.aux.jars.path</name>
    <value>/usr/local/src/atlas/apache-atlas-2.0.0/hook/hive</value>
</property>
  • 修改 HiveServer2 环境高级配置代码段

HIVE_AUX_JARS_PATH=/usr/local/src/atlas/apache-atlas-2.0.0/hook/hive
  • 将配置好的Atlas包发往各个hive节点后重启集群
scp -r /usr/local/src/atlas/apache-atlas-2.0.0 root@cdh02.cm:/usr/local/src/atlas/

scp -r /usr/local/src/atlas/apache-atlas-2.0.0 root@cdh02.cm:/usr/local/src/atlas/

重启集群

  • 将atlas配置文件copy到/etc/hive/conf下(集群各个节点)
scp /usr/local/src/atlas/apache-atlas-2.0.0/conf/atlas-application.properties root@cdh01.cm:/etc/hive/conf

scp /usr/local/src/atlas/apache-atlas-2.0.0/conf/atlas-application.properties root@cdh02.cm:/etc/hive/conf

scp /usr/local/src/atlas/apache-atlas-2.0.0/conf/atlas-application.properties root@cdh03.cm:/etc/hive/conf

2.6 启动 Atlas

#启动
./bin/atlas_start.py
#停止:./bin/atlas_stop.py

注意监控日志,看是否报错。主要日志application.log

2.7 将 Hive 元数据导入 Atlas

  • 所有节点添加hive环境变量
vim /etc/profile
#>>>
#hive
export HIVE_HOME=/opt/cloudera/parcels/CDH-6.2.0-1.cdh6.2.0.p0.967373/lib/hive
export HIVE_CONF_DIR=/etc/hive/conf
export PATH=$HIVE_HOME/bin:$PATH
#<<<
    
source /etc/profile
  • 执行atlas脚本
./bin/import-hive.sh
#输入用户名:admin;输入密码:admin(如修改请使用修改的)

体验一下吧
