Subject Re: Storm Kafka version mismatch issues
Date Sat, 13 Jan 2018 20:15:40 GMT
Stig,

This project is still in a POC status, so I can wipe and restart
anything...no big deal.  Thanks!  So, I am now seeing some build errors
when I try to run my assembly.  Is there a different method for setting up
the KafkaSpout?

[error]

and here is the relevant part of my topology:

// Set up the Kafka Spout
val zkHosts: BrokerHosts = new ZkHosts("r7u07:2181,r7u08:2181,r7u09:2181")
val pcapKafkaTopic: String = "packets"
val pcapZkRoot: String = "/packets"
val pcapClientId: String = "PcapKafkaSpout"

val pcapKafkaConf: SpoutConfig = new
SpoutConfig(zkHosts,pcapKafkaTopic,pcapZkRoot,pcapClientId)
pcapKafkaConf.ignoreZkOffsets = true
pcapKafkaConf.useStartOffsetTimeIfOffsetOutOfRange = true
pcapKafkaConf.startOffsetTime = kafka.api.OffsetRequest.EarliestTime
pcapKafkaConf.outputStreamId = "packets"
pcapKafkaConf.scheme = new SchemeAsMultiScheme(new PcapRecordKafkaScheme)

val pcapKafkaSpout = new KafkaSpout(pcapKafkaConf)

// Generates list of PCAP files to process, periodically scanning a
magic directory for new files
topologyBuilder.setSpout("pcapKafkaSpout", pcapKafkaSpout,PcapFileSpoutWorkers)
    .setNumTasks(PcapFileSpoutTasks)
    .setMemoryLoad(16 * 1024)
