1:Hbase启动hbase shell运行命令报Class path contains multiple SLF4J bindings.错误,是因为jar包冲突了,所以对于和hadoop的jar包冲突的,可以将其他jar包删除,如果你不确定是否删除正确,可以将其他的jar包复制备份或者修改名称,确保操作以后失败了,还可以找回。
SLF4J: Class path contains multiple SLF4J bindings.SLF4J: Found binding in [jar:file:/home/hadoop/soft/hbase-0.98.6-cdh5.3.6/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: Found binding in [jar:file:/home/hadoop/soft/hadoop-2.5.0-cdh5.3.6/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.SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]2018-04-08 05:32:06,305 WARN [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
2、我的操作是将其他的jar包修改了名称,这样也可以解决jar包冲突的问题。
[hadoop@slaver1 ~]$ cd /home/hadoop/soft/hbase-0.98.6-cdh5.3.6/lib/
[hadoop@slaver1 lib]$ mv slf4j-log4j12-1.7.5.jar slf4j-log4j12-1.7.5.jar-copy
之后再在hbase shell执行命令就不会出错了;
