Description
I am trying to use the RedisIO connector with Redis cluster but it looks like the Jedis client that RedisIO uses only works on a standalone Redis server, not on a cluster. I get this error when trying to read from Redis:
Exception in thread "main" org.apache.beam.sdk.Pipeline$PipelineExecutionException: redis.clients.jedis.exceptions.JedisMovedDa

This is the code that I use:
PCollection<Event> events =
pipeline
/*
* Step #1: Read from Redis.
*/
.apply("Read Redis KV Store", RedisIO.read()
.withEndpoint(redisHost, 6379)
.withKeyPattern(redisKeyPattern))
Is there a way to configure RedisIO to work with a cluster? I would have expected it to use JedisCluster when working with Redis in cluster mode but from https://github.com/apache/beam/blob/master/sdks/java/io/redis/src/main/java/org/apache/beam/sdk/io/redis/RedisIO.java it appears that it only uses the standalone Jedis client.
