         今天搭建hbase的时候启动hbase的时候shell面板输入了一大堆日志，如下：

        划重点：SLF4J: Class path contains multiple SLF4J bindings（  类路径包含多个绑定的意思）

        SLF4J: Found binding in [jar:file:/opt/software/hadoop-3.1.3/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/software/hbase/lib/client-facing-thirdparty/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

        这上面输入了三台节点hadoop的slf4j-log4j12-1.7.25.jar的jar包和hbase的slf4j-log4j12-1.7.25.jar的jar包版本都一样所以不是兼容性问题，所以是类路径包含多个SLF4J绑定。

        解决方法：

        在hbase的hbase-env.sh文件中进行修改（如果有这一行的话就把注释去掉，是其配置生效）或者增加（如果没有这一行配置，就增加到文件中）。

HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP=true 

        修改完成之后，重启hbase

        现在就简单清爽的很快了！当然非强迫患者，这个也可以不修改，不过对以后日志输出增加巨大的冗余。
