环境:redis.3.0 CentOS-6.4
运行上述程序后报错:redis.clients.jedis.exceptions.JedisClusterMaxRedirectionsException: Too many Cluster redirections?(大概意思是 连接数太多重定向了吗？！) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:34) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:67) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:83) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:67) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:83) at redis.clients.jedis.JedisClusterCommand.runWithRetries(JedisClusterCommand.java:67) at redis.clients.jedis.JedisClusterCommand.run(JedisClusterCommand.java:29) at redis.clients.jedis.JedisCluster.set(JedisCluster.java:70) at com.lm.test1.JedisTest.testJedisCluster(JedisTest.java:67) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access000(ParentRunner.java:41) at org.junit.runners.ParentRunner
解决方案：
第一种：在创建cluster的时候，带上超时时间和最大重定向数。
JedisCluster cluster=new JedisCluster(nodes,3000,1000);
第二种：查看 cluster nodes 信息
get cluster1 -> Redirected to slot [8483] located at 127.0.0.1:7002 "Hello World!"
连接超时，配置集群详细ip
