Having multiple logstash instances (more than one server) for reading from same s3 bucket using s3 input plugin

Would like to run logstash instances on two servers for High availability. Would like to know how to configure logstash to read from the same S3 bucket so that if one logstash server goes down other logstash instance can continue to read and process the data. This is similar to reading from a Kafka topic by two logstash instances installed on different logstash servers.
