Logstash error with redis and elasticsearch

HI Team,

I am getting below error when I am trying to start logstash service for redis

Can you please let me where I am doing wrong. Below are the version I am using

redis-3.2.0-1.el6.remi.x86_64
logstash-2.3.2-1.noarch
elasticsearch-2.3.3-1.noarch

Perhaps if you can provide your config we can help.
