             Summary: Multiple SLF4J bindings using Storm compatibility layer
                 Key: FLINK-2337
                 URL: https://issues.apache.org/jira/browse/FLINK-2337
             Project: Flink
          Issue Type: Bug
          Components: flink-contrib
            Reporter: Matthias J. Sax
            Assignee: Matthias J. Sax
            Priority: Minor


Storm depends on logback as slf4j implemenation but Flink uses log4j. The log shows the following conflict:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/cicero/.m2/repository/ch/qos/logback/logback-classic/1.0.13/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/cicero/.m2/repository/org/slf4j/slf4j-log4j12/1.7.7/slf4j-log4j12-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Need to exclude logback from storm dependencies to fix this.
