             Summary: Remove SLF4J warning messages on pio command 
                 Key: PIO-100
                 URL: https://issues.apache.org/jira/browse/PIO-100
             Project: PredictionIO
          Issue Type: Improvement
            Reporter: Shinsuke Sugaya
            Assignee: Shinsuke Sugaya
            Priority: Minor


pio command prints SLF4J warning as below:

{code}
$ /usr/share/predictionio/bin/pio status
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/share/predictionio/lib/spark/pio-data-hdfs-assembly-0.11.1-v1-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/share/predictionio/lib/pio-assembly-0.11.1-v1-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
...
{code}

The cause is that pio-data-hdfs contains slf4j-log4j12 jar file.
