DataSophon集成ApacheImpala的过程

刘圆辉2024-10-31 16:01

注意: 本次安装操作系统环境为Anolis8.9(Centos7和Centos8应该也一样)

DataSophon版本为DDP-1.2.1

整合的安装包我放网盘了:

通过网盘分享的文件：impala-4.4.1.tar.gz等2个文件

链接: https://pan.baidu.com/s/18KfkO_BEFa5gVcc16I-Yew?pwd=za4k 提取码: za4k

  1. Apache Impala的版本我选择的是目前Github上的最新版本4.4.1

Github上 Impala提供了rpm和deb两种安装方式,由于编译源码涉及到python包以及C++包机器难下载,所以我选择了Github提供的rpm包(注意RPM包中没有包含shell目录 deb包中是有的,如果使用rpm包的话,需要手动将这个shell文件夹拷贝进来).

  1. 首先下载apache-impala-4.4.1-RELEASE_hive-3.1.3-x86_64.el8.8.rpm

将rpm包移动到/opt目录下,然年执行yum安装

bash 复制代码 
wget https://github.com/apache/impala/releases/download/4.4.1/apache-impala-4.4.1-RELEASE_hive-3.1.3-x86_64.el8.8.rpm
mv apache-impala-4.4.1-RELEASE_hive-3.1.3-x86_64.el8.8.rpm /opt
yum install -y apache-impala-4.4.1-RELEASE_hive-3.1.3-x86_64.el8.8.rpm

记得安装好之后将shell文件夹拷贝进来啊

  1. 安装之后得到/opt/impala文件夹,重命名为/opt/impala-4.4.1
bash 复制代码 
cd /opt
mv impala impala-4.4.1
  1. 修改conf/impala-env.sh脚本命令,修改以下三个的值
bash 复制代码 
: ${JAVA_HOME:=/usr/local/jdk}

# Specify extra CLASSPATH.
: ${CLASSPATH:=${IMPALA_HOME}/conf/:${IMPALA_HOME}/lib/jars/*}

# Specify extra LD_LIBRARY_PATH.
: ${LD_LIBRARY_PATH:=${IMPALA_HOME}/lib/native/:${JAVA_HOME}/jre/lib/amd64/server/}
  1. 在conf下将Hadoop的core-site.xml hdfs-site.xml以及hive的core-site.xml拷贝进来

hive-site.xml内容我只放了这些

XML 复制代码 
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/user/hive/warehouse</value>
    </property>
    <property>
        <name>hive.metastore.port</name>
        <value>9083</value>
    </property>
    <property>
        <name>hive.metastore.uris</name>
        <value>thrift://node01:9083</value>
    </property>

    <property>
        <name>hive.metastore.event.db.notification.api.auth</name>
        <value>false</value>
    </property>
    <property>
        <name>hive.metastore.dml.events</name>
        <value>true</value>
    </property>
    <property>
	    <name>hive.metastore.transactional.event.listeners</name>
	    <value>org.apache.hive.hcatalog.listener.DbNotificationListener</value>
    </property>

</configuration>
  1. 打包tar.gz,并拷贝到DDP/packages目录下以及生成md5文件
bash 复制代码 
cd /opt
# 打包tar.gz
tar -zcvf impala-4.4.1.tar.gz impala-4.4.1
# 将tar.gz包拷贝到DDP/packages目录下
cp impapa-4.4.1.tar.gz /opt/datasophon/DDP/packages
cd /opt/datasophon/DDP/packages
# 生成md5文件
java -jar file-md5-1.0-SNAPSHOT-jar-with-dependencies.jar impala-4.4.1.tar.gz
  1. 编写IMPALA的service_ddl.json配置文件
bash 复制代码 
cd /opt/datasophon/datasophon-manager-1.2.1/conf/meta/DDP-1.2.1/
mkdir IMPALA
cd IMPALA
# 创建json文件并写入内容
vi service_ddl.json
bash 复制代码

  1. 重启datasophon的api服务
bash 复制代码 
cd /opt/datasophon/datasophon-manager-1.2.1/
启动：sh bin/datasophon-api.sh start api
停止：sh bin/datasophon-api.sh stop api
重启：sh bin/datasophon-api.sh restart api
  1. 回到网页中就可以进行服务的安装了(注意安装过程中修改catalogd以及satastored所在的服务器的ip或者host名称)

由于我的目录设置为/var/log/impala, impala并没有权限进行创建该目录,只能手动创建(这个问题我知道咋解决),这个步骤要在安装服务之前就做吧.

bash 复制代码 
mkdir -p /var/log/impala/minidumps
chmod 777 /var/log/impala
chmod 777 var/log/impala/minidumps
  1. 另外记得修改下环境变量,,DDP的环境变量在/etc/profile.d/datasophon-env.sh
bash 复制代码 
cat /etc/profile.d/datasophon-env.sh

# 内容如下
export JAVA_HOME=/usr/local/jdk1.8.0_333
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME CLASSPATH

export KYUUBI_HOME=/opt/datasophon/kyuubi-1.7.3
export SPARK_HOME=/opt/datasophon/spark-3.1.3
export PYSPARK_ALLOW_INSECURE_GATEWAY=1
export HIVE_HOME=/opt/datasophon/hive-3.1.0
export IMPALA_HOME=/opt/datasophon/impala-4.4.1
export KAFKA_HOME=/opt/datasophon/kafka-2.4.1
export HBASE_HOME=/opt/datasophon/hbase-2.4.16
export FLINK_HOME=/opt/datasophon/flink-1.17.1
export HADOOP_HOME=/opt/datasophon/hadoop-3.3.3
export HADOOP_CONF_DIR=/opt/datasophon/hadoop-3.3.3/etc/hadoop
export PATH=$PATH:$JAVA_HOME/bin:$SPARK_HOME/bin:$HADOOP_HOME/bin:$HIVE_HOME/bin:$IMPALA_HOME/bin:$IMPALA_HOME/sbin:$IMPALA_HOME/shell:$FLINK_HOME/bin:$KAFKA_HOME/bin:$HBASE_HOME/bin
export HADOOP_CLASSPATH=`hadoop classpath`
