Hi , As far as I can see, Kylin should be installed on a separated Gateway node in CDH cluster. In gateway node, you should not install any long running process/component such as data node/region server/node manager. Instead with some gateway role to let you have access to HDFS/HBase/Yarn/Hive etc. Following screenshot is a gateway node in my test env. [cid:[email protected]]

There are some suggestions for your doubts: 1. You need to add environment variable SPARK_HOME=/local/path/to/spark so that you can start kylin successfully even though you don't use spark to build cube. And you'd better using suggested version of spark(spark-2.3.2), you can download it by ./$KYLIN_HOME/bin/down-spark.sh . 2. Kylin supported cdh vertion is cdh5.7+, cdh6.0, cdh6.1 and you don't have to care about HBase version if you are using cdh. In case you are using cdh5.16, you can download apache-kylin-<version>-bin-cdh57.tar.gz from http://kylin.apache.org/download/ 3. You don't have to install kylin on master node, any other node in cluster would be OK. ------------------- Best wishes, Rupeng Wang 发件人: Gourav Gupta <[email protected]> 日期: 2019年8月30日 星期五 02:03 收件人: Wang rupeng <[email protected]> 抄送: "[email protected]" <[email protected]> 主题: Re: Unable to create cube in Spark Mode -Apache Kylin on Cloudera Thanks a lot Wang for the prompt helpful reply. Actually today I have removed the old version of Kylin and installed successfully apache Kylin 2.6 for CDH mode but now at this time, we are unable to open Kylin WEB UI. Even though I have had changed port number 7070 to some other number in server.xml(Tomcat directory), but still facing the same issue. I have some doubts while configuring the Kylin which are mentioned below: 1. Would I have to write the path of spark master node or path of spark which has come with Kylin? 2.Which tar file will be suitable for cloudera 5.16 ?? What is the need of Kylin-HBase version? 3.should I need to install and configured Kylin on master node? will installation over the edge node work? Actually, we are trying to switch the visualization layer from SQL(OLAP) - PowerBI pipeline to KYLIN-Mean Stack (Open Source/Enterprise version ). So your help is much appreciated on the same. I am waiting for your positive response.
