Subject [jira] [Commented] (FLINK-2337) Multiple SLF4J bindings using Storm compatibility layer
Date Fri, 10 Jul 2015 18:02:05 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14622669#comment-14622669

ASF GitHub Bot commented on FLINK-2337:

Github user mjsax commented on the pull request:

    Travis failed due to unrelated error:
        Failed tests: 
The program encountered a ProgramInvocationException : The program execution failed: Job execution
    Does anyone know anything about this failing test?
    The log warning `SLF4J: Class path contains multiple SLF4J bindings.` is gone for the
4 successful Travis runs.
    This PR should be ready to get merged.

>             Project: Flink
>          Issue Type: Bug
>          Components: flink-contrib

>            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.
