Qili Chen created STORM-2852:
--------------------------------
Summary: Dup log4j jars in storm-local
Key: STORM-2852
URL: https://issues.apache.org/jira/browse/STORM-2852
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Affects Versions: 1.0.2
Environment: Mac
Reporter: Qili Chen
After upgrading to 1.0.2, every time there was "Could not initialize class
org.apache.log4j.Log4jLoggerFactory" error when deploying a topology, but
nothing suspicious found against the dependency tree.
Turned out there are dup log4j implementation jars under storm lib dir
log4j-over-slf4j-1.6.6.jar
log4j-slf4j-impl-2.1.jar
After removing log4j-over-slf4j-1.6.6.jar from lib, the whole world is running
well.
Could you someone help fix? It's quite tricky to figure out the problem
