Automatically reconnect Storm Topology to Redis Cluster on Redis restart

$

0

I have created a Storm topology which connects to Redis Cluster using Jedis library. Storm component always expects that Redis is up and running and only then it connects to Redis and subscribes the events.Currently we use pub-sub strategy of Redis.

Below is the code sample that explains my Jedis Connectivity inside Storm to for Redis.

try {    jedis.psubscribe(listener, pattern);} catch(Exception ex) {    //catch statement here.} finally {    pool.returnResource(jedis);}....pool = new JedisPool(new JedisPoolConfig(), host, port); //redis host portListenerThread listener = new ListenerThread(queue, pool, pattern);listener.start();

EXPECTED BEHAVIOUR

Once Redis dies and comes back online, Storm is expected to identify the status of Redis. It must not need a restart in case when Redis die and come online.

ACTUAL BEHAVIOUR

Once Redis restarts due to any reason, I always have to restart the Storm topology as well and only then it starts listening back to Redis.

QUESTION

How can I make Storm listen and reconnect to Redis again after Redis is restarted? any guidance would be appreciated, viz. docs, forum answer.
