Questions about multiple kylin servers
I have configuered 3 kylin servers. One is in "all" mode, others are in "query" mode. On top of the servers, I use a ngnix server.
Then tableau is used to connect to the ngnix server to map to one of the kylin servers. While when I drap some sqls on tableau, some of the kylin servers will no responsing, with no error log. The web ui is also unable to load cubes. Is anyone faced the same problem?

When 'KYLIN_JVM_SETTINGS' configuration is set, tomcat's configuration is also set the same time.

I think I found the cause. I increased the 'kylin.query.mem.budget', with the 'KYLIN_JVM_SETTINGS' no changed. I think maybe this caused the kylin server no responding when I execute a big query.
Is the 'KYLIN_JVM_SETTINGS' how much memory allocated to Kylin server? If I changed this parameter, will I need to change the tomcat JAVA_OPTS?

i think you need to check ngnix log and make sure the request is forwarded
to the 3 kylin servers.

I think I found the cause. I increased the 'kylin.query.mem.budget', with the 'KYLIN_JVM_SETTINGS' no changed. I think maybe this caused the kylin server no responding when I execute a big query.
Is the 'KYLIN_JVM_SETTINGS' how much memory allocated to Kylin server? If I changed this parameter, will I need to change the tomcat JAVA_OPTS?
