# Jedis cluster模式连接出现No more cluster attempts left
同事在测试环境jedis cluster模式出现redis.clients.jedis.exceptions.JedisClusterMaxAttemptsException: No more cluster attempts left.
报错,找到我帮忙定位下问题
通过堆栈信息找到对应的源码位置redis.clients.jedis.JedisClusterCommand#runWithRetries
private T runWithRetries(final int slot, int attempts, boolean tryRandomNode, JedisRedirectionException redirect) {
if (attempts <= 0) {
throw new JedisClusterMaxAttemptsException("No more cluster attempts left.");
}
...
}
从源码中分析得到,在测试attempts
次之后就会抛出No more cluster attempts left
的异常,根据源码下文有两种异常会导致重试
- JedisConnectionException:连接redis出现异常
- JedisRedirectionException:redis重定向会抛出的异常,比如MOVE
在对应的位置打上断点,运行出现问题的接口,出现以下报错
问题就很明显了,ERR Client sent AUTH, but no password is set
,意思是项目配置设置了密码,但是这个redis节点没有设置密码,是运维的同学漏配置了
