Kyuubi基本安装与使用指南

Apache Kyuubi (Incubating)，一个分布式和多租户网关，用于在 Lakehouse 上提供无服务器 SQL。本文为kyuubi入门文章，介绍了Kyuubi基本安装与使用，并以Spark引擎为例讲述如何提交第一个Spark SQL任务。

安装包下载

进入如下页面下载kyuubi安装包：https://kyuubi.apache.org/releases.html，下面以1.5.0-incubating版本为例。

mkdir /data && cd /data
wget https://dlcdn.apache.org/incubator/kyuubi/kyuubi-1.5.0-incubating/apache-kyuubi-1.5.0-incubating-bin.tgz
tar zxvf apache-kyuubi-1.5.0-incubating-bin.tgz
ln -s apache-kyuubi-1.5.0-incubating-bin kyuubi


由于我们这边使用的是spark引擎，所以还需要下载spark安装包

cd /data
wget https://www.apache.org/dyn/closer.lua/spark/spark-3.2.1/spark-3.2.1-bin-hadoop3.2.tgz
tar zxvf spark-3.2.1-bin-hadoop3.2.tgz
ln -s spark-3.2.1-bin-hadoop3.2 spark

修改配置文件

cd conf
cp spark-env.sh.template spark-env.sh

vim spark-env.sh

设置HADOOP_CONF_DIR

export HADOOP_CONF_DIR=/etc/hadoop/conf

测试spark任务是否能提交到yarn上

bin/spark-submit --master yarn --class org.apache.spark.examples.SparkPi ./examples/jars/spark-examples_2.12-3.2.1.jar

得到如下结果

配置文件修改

修改配置文件

cd /data/kyuubi
cd conf
cp kyuubi-defaults.conf.template kyuubi-defaults.conf
cp kyuubi-env.sh.template kyuubi-env.sh
cp log4j2.properties.template log4j2.properties


上述文件各项配置参数可参考：https://kyuubi.apache.org/docs/latest/deployment/settings.html

下面以HDP 3.1.4为例

kyuubi-env.sh内容如下

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-1.el7_9.x86_64
export SPARK_HOME=/data/spark
export HADOOP_CONF_DIR=/etc/hadoop/conf
export KYUUBI_JAVA_OPTS="-Xmx6g -XX:+UnlockDiagnosticVMOptions -XX:ParGCCardsPerStrideChunk=4096 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly -XX:+CMSClassUnloadingEnabled -XX:+CMSParallelRemarkEnabled -XX:+UseCondCardMark -XX:MaxDirectMemorySize=1024m  -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=./logs -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintTenuringDistribution -Xloggc:./logs/kyuubi-server-gc-%t.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=5M -XX:NewRatio=3 -XX:MetaspaceSize=512m"

kyuubi-defaults.conf内容如下

kyuubi.ha.zookeeper.quorum  hadoop1:2181,hadoop2:2181,hadoop3:2181
spark.master                yarn

log4j2.properties文件可不修改

启动kyuubi

bin/kyuubi start

可以看到kyuubi已经启动

使用beeline连接kyuubi

 bin/beeline -u "jdbc:hive2://hadoop1:2181,hadoop2:2181,hadoop3:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=kyuubi" -n hdfs

得到

查看YARN UI

提交测试任务
