Hi there! I want to use redis cluster instant of one instance. here is my framework：  
logstash shipper -\>redis cluster -\> logstash indexer -\> elasticsearch -\> kibana

Here is my redis config:

> [root@localhost src]# ./redis-trib.rb info 192.168.1.153:4000  
> 192.168.1.153:4000 (4c017302...) -\> 0 keys | 5461 slots | 0 slaves.  
> 192.168.1.153:4002 (12b14519...) -\> 1 keys | 5461 slots | 0 slaves.  
> 192.168.1.153:4001 (59ca7fa9...) -\> 0 keys | 5462 slots | 0 slaves.  
> [OK] 1 keys in 3 masters.  
> 0.00 keys per slot on average.  
> [root@localhost src]# redis-cli -c -p 4000  
> 127.0.0.1:4000\> set "test" "test"  
> -\> Redirected to slot [6918] located at 192.168.1.153:4001  
> OK  
> 192.168.1.153:4001\> set "abc" "abc"  
> OK  
> 192.168.1.153:4001\> set "hello" "world"  
> -\> Redirected to slot [866] located at 192.168.1.153:4000  
> OK  
> 192.168.1.153:4000\>

Here is my logstash shipper config:

> input{  
> log4j {  
> port =\> 4561  
> type =\> "log4j-json-test"  
> }  
> }  
> output{  
> redis {  
> data\_type =\> "list"  
> host =\> "192.168.1.153:4000"  
> key =\> "logstash\_test"  
> }  
> }

Here is my logstash indexer config:

> input{  
> redis{  
> host =\> "192.168.1.153"  
> port =\> 4000  
> key =\> "logstash\_test"  
> data\_type =\> "list"  
> }  
> }  
> output{  
> elasticsearch {  
> hosts =\> "192.168.1.153"  
> }  
> }

Here is the logstash shipper error log:

> [jason@localhost logstash]$ ./logstash-2.1.1/bin/logstash agent -f conf/client1.conf  
> Settings: Default filter workers: 2  
> Logstash startup completed  
> Failed to send event to Redis {:event=\>#\<LogStash::Event:0x1c747a72 @metadata={}, ...................

Here is the logstash indexer error log(I think the resason is not the same with shipper error):

> Redis connection problem {:exception=\>#\<Redis::CommandError: CROSSSLOT Keys in request don't hash to the same slot\>, :level=\>:warn}

I'd put the port number in quotes.

Ofcourse,they are on the same server.

I suspect that the configuration was not correct.
