推荐理由：kylin官网目前支持的hive最高版本为1.2.1, 而阿里云最低版本的hive也在2.X, 因此直接按照官网是安装不成功的. 下面这片文章非常好的总结了如何在阿里云emr机器上安装kylin, 具有非常良好的指导作用, 也有助于理解kylin是如何工作的.
根据下面的文章安装成功.
****NOTE****
注意替换kylin版本号和emr版本号.另外查一下emr环境下是否存在环境变量 JAVA_LIBRARY_PATH,该变量会将 /usr/lib/hive-current/lib/ 目录下的jar包加载进来导致jar包版本冲突(这个问题排查了很久). 使用
export JAVA_LIBRARY_PATH=:
去掉这个环境变量.
附:
1.编译是否有必要?根据后面的结果报错的原因在于没有使用hive-1.2.1的jar包(使用了****/usr/lib/hive-current/lib/ 目录下的jar包****), 不过时间原因没有尝试过.
2.由于设置了专门的环境变量, 在操作系统上新建一个用户(如kylin)来运行kylin会比较合适.
以下内容转自: 在阿里云EMR环境下部署Kylin
本人耗时约一天。
1 下载Kylin
wget http://mirrors.tuna.tsinghua.edu.cn/apache/kylin/apache-kylin-2.6.3/apache-kylin-2.6.3-bin-hbase1x.tar.gz
tar zxvf apache-kylin-2.6.3-bin-hbase1x.tar.gz
cd apache-kylin-2.6.3-bin-hbase1x
下文以解压到/home/hadoop为例。
2 设置环境变量
export KYLIN_HOME=pwd
export HIVE_CONF=/etc/ecm/hive-conf(你的EMR Hive配置文件路径)
export HADOOP_HOME=/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/hadoop-2.8.5-1.1.0
export HIVE_HOME=/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/apache-hive-1.2.1-bin
export SPARK_HOME=/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/spark-2.3.2-1.2.0-bin-hadoop2.8
3 准备必要文件：
3.1 把你的EMR Hadoop路径/opt/apps/ecm/service/hadoop/2.8.5-1.1.0/package/hadoop-2.8.5-1.1.0拷到/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/hadoop-2.8.5-1.1.0（具体路径可能不同）
3.2 下载一个Hive 1.2.1
wget https://archive.apache.org/dist/hive/hive-1.2.1/apache-hive-1.2.1-bin.tar.gz
并解压到/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/apache-hive-1.2.1-bin
3.3 把你的EMR Spark路径/opt/apps/ecm/service/spark/2.3.2-1.2.0/package/spark-2.3.2-1.2.0-bin-hadoop2.8拷到/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/spark-2.3.2-1.2.0-bin-hadoop2.8（具体路径可能不同）
3.4 建目录hadoop-conf并执行：
ln -s /etc/ecm/hadoop-conf/core-site.xml $KYLIN_HOME/hadoop-conf/core-site.xml
ln -s /etc/ecm/hadoop-conf/hdfs-site.xml $KYLIN_HOME/hadoop-conf/hdfs-site.xml
ln -s /etc/ecm/hadoop-conf/yarn-site.xml $KYLIN_HOME/hadoop-conf/yarn-site.xml
ln -s /etc/ecm/hbase-conf/hbase-site.xml $KYLIN_HOME/hadoop-conf/hbase-site.xml
ln -s /etc/ecm/hive-conf/hive-site.xml $KYLIN_HOME/hadoop-conf/hive-site.xml
再编辑conf/kylin.properties
改一句：kylin.env.hadoop-conf-dir=/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/hadoop-conf
4 替换Tomcat
自带的tomcat有问题，把里面的webapps/kylin.war拷出来备份，再删掉tomcat目录，然后下载一个Tomcat 8：
wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.43/bin/apache-tomcat-8.5.43.tar.gz
解压并重命名为tomcat，再把kylin.war拷进webapps。
修改conf/server.xml中的Web端口为7070。
执行:
rm ./tomcat/webapps/kylin/WEB-INF/lib/slf4j-api-1.7.21.jar
cp ./hadoop-2.8.5-1.1.0/share/hadoop/common/lib/slf4j-api-1.7.10.jar ./tomcat/webapps/kylin/WEB-INF/lib/

访问http://机器名:7070/kylin/
使用admin/KYLIN登录。如果404则是出现了错误，在$KYLIN_HOME/logs下有日志。
一些错误的解决：
6.1 报找不到.keystore
直接mkdir conf/.keystore
6.2 报找不到contrib/capacity-scheduler/*.jar
直接mkdir -p hadoop-2.8.5-1.1.0/contrib/capacity-scheduler/
在该目录下touch dummy再zip -r dummy.jar dummy
6.3 报More than one fragment with the name org_apache_tomcat_websocket
删除tomcat/webapps/kylin/WEB-INF/lib/jul-to-slf4j-1.7.5.jar及jcl-over-slf4j-1.7.21.jar
6.4 报找不到HiveHook之类
cp /usr/lib/hive-current/lib/meta-hive-hook-1.0.1.jar apache-hive-1.2.1-bin/lib/
6.5 报loader constraint violation
rm tomcat/webapps/kylin/WEB-INF/lib/slf4j-api-1.7.21.jar
cp ./hadoop-2.8.5-1.1.0/share/hadoop/common/lib/slf4j-api-1.7.10.jar ./tomcat/webapps/kylin/WEB-INF/lib/

6.6 报找不到derbyLocale之类的jar包。
不用管，忽略即可。
7 准备样例数据
${KYLIN_HOME}/bin/sample.sh
如未成功请重新登录并修改环境变量:
export KYLIN_HOME=pwd
export HIVE_CONF=/etc/ecm/hive-conf(你的EMR Hive配置文件路径)
export HADOOP_HOME=/home/hadoop/apache-kylin-2.6.3-bin-hbase1x/hadoop-2.8.5-1.1.0
(即去掉步骤2中的最后两行)
到界面/System/执行Reload Metadata并刷新页面。
此时可以看到Model页出现kylin_sales_cube且状态为DISABLED。
8 Build样例数据
在界面/Model/action选择Build，选择2012年1月1日至2012年1月2日并确定，再去Monitor页查看结果。
约10分钟后成功，此时去Insight页面，在最上方的-- Choose Project --下拉框选择learn_kylin后，执行select count(*) from KYLIN_SALES应该会正确返回结果。
如果失败请查看Yarn错误日志或联系本人钉钉13699124376。
