Hi friend, I feel so glad to hear you have resolved some problem after a lot effort, and it is very kind of you to share something you found about kylin-port-replace-util.sh with us. It seems that you meet another trouble of the first step of your cube building, using Hive to create a flat table. As far as I can see, the message provided by you “FAILED: Execution Error, return code 3 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask”indicated that your Hive is NOT configured in right way. Your Hive command run in local mode other than Yarn mode. It is strange, did your node which you choose to deploy Kylin is configured in correct way? Maybe you should ask your Hadoop administrator for help. Or could you please provided more detail about how your deploy Kylin? If you use Kylin for the first time and you are familiar with Docker, maybe you can run a docker container to have a technical preview. Please refer to http://kylin.apache.org/docs/install/kylin_docker.html.

Truly appreciated!!! As the answers have been received from you, I did the port number amendment in "./$KYLIN_HOME/bin/Kylin-port-replace-util.sh set", but still thereafter I was facing with the same issue. After doing hours of brainstorming, I was able to resolve the aforesaid issue(Not able to access Kylin UI), Actually, one of the java application was running on 9009 port no. and we also know that Kylin takes 3 ports 7070,9009 & 7443. Was able to access the Kylin Web UI while I stopped the already running script on 9009. At this time I am facing with one caveat i.e "FAILED: Execution Error, return code 3 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask" when I am going to create a cube in Map-Reduce mode. I googled the same and did the amendment( Kylin and Hive property) as per the solution I got over the shared link(https://stackoverflow.com/questions/22977790/hive-query-execution-error-return-code-3-from-mapredlocaltask) but still, I am not able to resolve. Please let me know is there any way of resolving this issue. Attaching the screenshot of the error. Thanks in advance.

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 <techgouravgu...@gmail.com<mailto:techgouravgu...@gmail.com>> 日期: 2019年8月30日 星期五 02:03 收件人: Wang rupeng <wangrup...@live.cn<mailto:wangrup...@live.cn>> 抄送: "dev@kylin.apache.org<mailto:dev@kylin.apache.org>" <dev@kylin.apache.org<mailto:dev@kylin.apache.org>> 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.
