[jira] [Created] (KYLIN-2428) Cleanup unnecessary shaded libraries
for job/coprocessor/jdbc/server
Billy Liu created KYLIN-2428:
--------------------------------
Summary: Cleanup unnecessary shaded libraries for job/coprocessor/jdbc/server
Key: KYLIN-2428
URL: https://issues.apache.org/jira/browse/KYLIN-2428
Project: Kylin
Issue Type: Improvement
Components: General
Affects Versions: v1.6.0
Reporter: Billy Liu
Assignee: Billy Liu
Kylin releases three libraries: kylin-coprocessor, kylin-jdbc, kylin-job and one web application: server.
Currently, all libraries have shaded some used third party libraries into the package. For example, guava, curator, commons, kyro in kylin-job. The duplicate libraries in runtime classpath may have potential class loading conflicts and waste computing resource. We should leverage the hadoop provided libraries at runtime instead of the shaded one.
