    I am installing Storm on Hortonworks sandbox, I followed the instructions you send in this link: But, I could not launch storm due to the following exception:

    [root@sandbox conf]# storm-yarn launch /usr/storm-work/storm-0.9.0-wip21/conf/storm.yaml
    SLF4J: Class path contains multiple SLF4J bindings.
    SLF4J: Found binding in [jar:file:/usr/lib/hadoop/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
    SLF4J: Found binding in [jar:file:/usr/storm-work/storm-0.9.0-wip21/lib/logback-classic-1.0.6.jar!/org/slf4j/impl/StaticLoggerBin der.class]
    SLF4J: See for an explanation.
    SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
    Exception in thread “main” java.lang.UnsupportedClassVersionError: backtype/storm/utils/Utils : Unsupported major.minor version 5 1.0

    I would appreciate your help on troubleshooting this error. Also, if you think I should follow a different instructions for installing Storm on the sandbox please let me know.
