today on a new environment (EMR) with Kylin 1.5.3, I also encounter this " class path resource [kylin-server-log4j.pro perties] cannot be resolved to URL because it does not exist" error; I temporarily fixed it by copy the kylin-server-log4j.properties file from conf/ to tomcat/webapps/kylin/WEB-INF/classes;
The root cause is described in https://issues.apache.org/jira/browse/KYLIN-1963; After upgrading to the 1.5.4, the problem didn't occur. please have a try. 2016-08-11 22:39 GMT+08:00 ShaoFeng Shi <[email protected]>: > Hi tongxin, > > Have you found the solution?
