Subject [jira] [Created] (ACCUMULO-2926) Multiple slf4j bindings warning
Date Thu, 19 Jun 2014 00:53:25 GMT
Josh Elser created ACCUMULO-2926:

             Summary: Multiple slf4j bindings warning
                 Key: ACCUMULO-2926
             Project: Accumulo
          Issue Type: Bug
            Reporter: Josh Elser
            Assignee: Christopher Tubbs
             Fix For: 1.6.1, 1.7.0

ACCUMULO-2808 introduced slf4j-log4j12 into Accumulo's classpath which clashes with the hadoop
provided slf4j-log4j12 which prints out the lovely below message way too frequently.

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/lib/slf4j-log4j12.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/lib/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

I'm seeing this in master, but I imagine it also exists in 1.6.1.
