How to fetch kafka Message have [KEY,VALUE] pair

prateekarora
Hi

I am new for Apache Flink and start  using Flink version 1.0.1

In my scenario,   kafka message have key value pair [String,Array[Byte]] .

I tried to use FlinkKafkaConsumer08 to fetch data but i dont know how to write  DeserializationSchema for that.

val stream : DataStream[(String,Array[Byte])]  = env.addSource(new FlinkKafkaConsumer08[(String,Array[Byte])]("a-0",<DeserializationSchema> , properties))

please help me to solve this problem .

Regards
Prateek
