CDH中在命令行执行hbase shell时候报错如下：

[root@test-dev-cdh-1 lib]# hbase shell

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。

[root@test-dev-cdh-1 lib]# ls phoenix-5.0.0-HBase-2.0-client.jar
phoenix-5.0.0-HBase-2.0-client.jar
[root@test-dev-cdh-1 lib]# mv phoenix-5.0.0-HBase-2.0-client.jar phoenix-5.0.0-HBase-2.0-client.jar.back
[root@test-dev-cdh-1 lib]# ls phoenix-5.0.0-HBase-2.0-thin-client.jar
phoenix-5.0.0-HBase-2.0-thin-client.jar
[root@test-dev-cdh-1 lib]# mv phoenix-5.0.0-HBase-2.0-thin-client.jar phoenix-5.0.0-HBase-2.0-thin-client.jar.back
[root@test-dev-cdh-1 lib]# ls phoenix-5.0.0-HBase-2.0-pig.jar
phoenix-5.0.0-HBase-2.0-pig.jar
[root@test-dev-cdh-1 lib]# mv phoenix-5.0.0-HBase-2.0-pig.jar phoenix-5.0.0-HBase-2.0-pig.jar.back
[root@test-dev-cdh-1 lib]# 
[root@test-dev-cdh-1 lib]#

2、备份完了报冲突的jar包之后，重新执行hbase shell即可。

[root@test-dev-cdh-1 lib]# hbase shell
