Flume classpath包含多个SLF4J绑定，用于获取twitter数据

Question

使用命令获取twitter数据时：

./bin/flume-ng agent -n TwitterAgent -c conf -f /usr/lib/apache-flume-1.4.0-bin/conf/flume.conf

终端中的警告弹出窗口说：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/lib/apache-flume-1.7.0-bin/lib/slf4j-logj12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/lib/zookeeper/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticBinder
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

我正在使用quickstart cloudera 5.10和flume 1.7.0。
