hongbin ma created KYLIN-1963: --------------------------------- Summary: Delegate the loading of certain package (like slf4j) to tomcat's parent classloader Key: KYLIN-1963 URL: https://issues.apache.org/jira/browse/KYLIN-1963 Project: Kylin Issue Type: Improvement Reporter: hongbin ma Assignee: hongbin ma
currently we use hbase command to start tomcat, which then starts kylin as a web application. The default classloader that tomcats assigns to the kylin applications is WebappClassLoader, which will search local repositories before parent classloader. the design will lead to two separate log4j logging instances in both the "HBase space" and "kylin space", the two loggers will attempt to write to the same file, which is problematic according to official documents -- This message was sent by Atlassian JIRA (v6.3.4#6332)
