Falcon SERVER启动给我错误： 当我执行“ ./bin/falcon admin -version”时，它将在控制台上显示以下输出。
Hadoop is installed, adding hadoop classpath to falcon classpath
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/tmp/falcon/falcon-0.11/client/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/tmp/falcon/falcon-0.11/client/lib/falcon-shell-0.11.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]
