I have the following camel which polls Redis:
from("timer://pollredis?fixedRate=true&period=5")
// poll redis
.setHeader("CamelRedis.Command", constant("LPOP"))
.setHeader("CamelRedis.Key", constant("shipments"))
// from redis, it is a producer, fetch with .to() !
.to(redisUri)
//
.choice().when(simple("${in.body} == null")).stop().otherwise()
//
.to("direct:internal").end();
JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
jedisConnectionFactory.afterPropertiesSet();
RedisTemplate<?, ?> redisTemplate = new RedisTemplate();
redisTemplate.setConnectionFactory(jedisConnectionFactory);
redisTemplate.setDefaultSerializer(new StringRedisSerializer());
redisTemplate.afterPropertiesSet();
SimpleRegistry registry = new SimpleRegistry();
registry.put("redisTemplate", redisTemplate);
And it works great. However, when I change the redisUri from
redisUri = spring-redis://localhost:6379?redisTemplate=#redisTemplate
to
redisUri = spring-redis://[stuff].xavwv8.ng.0001.euw1.cache.amazonaws.com:6379?redisTemplate=#redisTemplate
I get the following error:

I have checked that I have access to the elasticache by telneting to it and by using redis-cli.
What is this Could not get a resource from the pool
error that I'm getting when connecting to a remote host?
Both my local redis and the elasticache redis is running 2.8.24. Running camel 2.17.1.
Here's how I got it working:
properties-file:
Camel route same as before.
So apparently when you use a connection factory you can't set the host to use in the URI later.
