每次执行 hbase shell 时，出现如下提示：
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/itcast/hbase-0.98.18-hadoop2/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/itcast/hadoop-2.6.0/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.
从提示信息来看，是hadoop的slf4j 与hbase的slf4j jar包发生了冲突，移除其中一个即可
执行：
rm -f /itcast/hbase-0.98.18-hadoop2/lib/slf4j-log4j12-1.6.4.jar
移除jar包即可
