Re: kafkaDirectStream usage error
2 things:
- you're only attempting to read from a single TopicAndPartition. Since
your topic has multiple partitions, this probably isn't what you want
- you're getting an offset out of range exception because the offset you're
asking for doesn't exist in kafka.
Use the other createDirectStream method (the one that takes a set of
topics, not a map of topicpartitions to offset), at least until you get an
understanding for how things work.

kafkaDirectStream usage error
I am using below directsream to consume messages from kafka . Topic has 8
partitions.
val topicAndPart = OffsetRange.create("request5",0,
1,10).topicAndPartition()
val fromOffsets = Map[kafka.common.TopicAndPartition,Long](topicAndPart->0)
val messageHandler = (mmd : MessageAndMetadata[String,String]) =>
(mmd.key(),mmd.message())
val k1 =
KafkaUtils.createDirectStream[String,String,StringDecoder,StringDecoder,(String,String)](ssc,
kafkaParams, fromOffsets,messageHandler)
I am getting below error . Any idea where I am doing wrong . Please
help .
