1 问题描述

新搭建了一个低版本的TDSQL 集群，但是在赤兔中不显示kafka的信息， 这个是老问题，之前遇到过一次，解决方法参考：

这次遇到了一个新问题，发现节点的collector 无法启动。

2 解决方法

通过上面的日志，可以定位出是java.lang.ClassNotFoundException: org.apache.log4j.Level 导致的问题，这里实际上是2个jar包导致的故障。 http://www.cndba.cn/cndba/dave/article/4620

SLF4J: Found binding in [jar:file:/data/application/collector/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/data/application/collector/lib/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]

我们查看环境变量：

[root@www.cndba.cn 2 collector]# cat /etc/profile
# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

这里的路径较多，我们搜索对应jar包：

这里也确实存在多个版本的jar包，既然定位到了问题，我们直接删除掉collector 的jar包：

再次重启collector，成功：
