Christopher Tubbs commented on ACCUMULO-2926: --------------------------------------------- You will need to update your classpath to only include one. This has already been updated in 1.6.1 and later's classpath template at conf/templates/accumulo-site.xml in ACCUMULO-2808. For the other example config files, we should do ACCUMULO-2646. > Multiple slf4j bindings warning > ------------------------------- > > Key: ACCUMULO-2926 > URL: https://issues.apache.org/jira/browse/ACCUMULO-2926 > Project: Accumulo > Issue Type: Bug > Environment: apache hadoop 2.4.0 > 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. > {noformat} > 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 http://www.slf4j.org/codes.html#multiple_bindings for an > explanation. > SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory] > {noformat} > I'm seeing this in master, but I imagine it also exists in 1.6.1. -- This message was sent by Atlassian JIRA (v6.2#6252)
