Hello again, I forgot to mention that I use IE or Secured Firefox as Web browsers. I have the same issue with both. Could there be the cause of the problem ?
Best regards Jean-Luc. De : BELLIER Jean-luc Envoyé : vendredi 2 février 2018 14:48 À : user <email@example.com> Objet : RE: Problem starting Kylin Web interface Hello Thank you for your answer. I did the following : · rename my current kylin.log and kylin.out files to keep a trace · restarted the commands ‘kylin.sh start’ and ‘sample.sh’ I cannot see anything special in the new .log or .out files. The Hive tables exist, and the kylin_metadata also. I can scan it through Hbase shell command. It gives me 44 rows. However, the problem is still the same with the Kylin Interface : Models loading indefinitely, no table displayed, and nothing in the ‘System’ section. When I try to refresh the server config and the server environement, I still have the message ‘Oops ! Failed to take action. I also have this message as soon as I click to the ‘System’ button. Should I rebuild the project from scratch to be sure that everything is correctly created, or should I investigate somewhere else (services, node states, …) ? I send in attachement the now kylin.log and kylin.out files Thank you in advance for your help. Have a good day. Best regards, Jean-Luc.

The kylin.out has some error about missing ".keystore", but by default if you accessing kylin via http, it shouldn't need to load keystore. Please try visit http://host:7070/kylin again to see whether there is any issue in the web console. 2018-02-01 23:17 GMT+08:00 BELLIER Jean-luc <jean-luc.bell...@rte-france.com<mailto:jean-luc.bell...@rte-france.com>>: Hello, I am new in Kylin. I would like to test it for a POC for my company. I opened a ticket yesterday in the issues mail box through Jira, but I am not sure it is the best place. Here is the reference of the ticket : https://issues.apache.org/jira/browse/KYLIN-3218 I am using the version apache-kylin-2.2.0-bin-cdh57, with Linux. I installed the software on a client node. I successfully started the process and created the cube given in the example project. Apparently, no mistake appears when starting the kylin.sh shell or generating the cube using sample.sh. When I launch the web interface using <nodename>:7070/kylin, I cannot load the models (the cursor is turning indefinitely). By looking at the kylin.out log, I could see that the process could not find the $KYLIN_HOME/tomcat/conf/.keystore file. So I created it manually, and relaunched the cube generation and the ‘kylin.sh start’ command. Now I face to other mistakes : • Exception in thread "Thread-14" java.lang.RuntimeException: Error while peeking at /kylin/kylin_metadata/job_engine/global_job_engine_lock • SEVERE: The web application [/kylin] appears to have started a thread named [TGT Renewer for bellier...@hades.rte-france.com<mailto:bellier...@hades.rte-france.com>] but has failed to stop it. This is very likely to create a memory leak. This one appears several times • SEVERE: The web application [/kylin] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@10cb8259]) and a value of type [org.apache.kylin.rest.msg.Message] (value [org.apache.kylin.rest.msg.Message@267ae210]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. This one appears several times Apparently, something else is missing, or I did something wrong, but I do not know what. I would also like to know what will be the impact of the two ‘SEVERE’ issues above and how I could correct it. I attach the last version of kylin.out file. Any help would be kindly appreciated. Thank you in advance for your help. Have a good day. Best regards. Jean-Luc.
