Kafka adminclient API - get(TopicPartition) is ambiguous for the type Map
0
This is my code:
Properties props2 = new Properties();
props.put(CommonClientConfigs.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
AdminClient adminClient = AdminClient.create(props);
scala.collection.immutable.Map<TopicPartition,Object> offsets =
adminClient.listGroupOffsets("foo");
Option<Object> offset = offsets.get(new TopicPartition("test", 0));
System.out.println(Long.parseLong(offset.get().toString()));
I am using kafka_2.11_0.10.2.1 and kafka-clients_0.10.2.1. offsets.get() has a compiled problem: The method get(TopicPartition) is ambiguous for the type Map<TopicPartition,Object>.How should I solve it?

This might not be the most optimal way to do it, but it's certainly a workaround.
