Getting noclassfoundexception when integrating flume-kafka - apache-kafka

Question

I am using Flume and trying to publish the output "/usr/bin/vmstat 1" to a kafka topic.
But I get exceptions as mentioned in the stack trace. Please help me to find solution to the problem.

Flume Config
tier1.sources = source1
tier1.channels = channel1
tier1.sinks = sink1
tier1.sources.source1.type = exec
tier1.sources.source1.command = /usr/bin/vmstat 1
tier1.sources.source1.channels = channel1
tier1.channels.channel1.type = memory
tier1.channels.channel1.capacity = 10000
tier1.channels.channel1.transactionCapacity = 1000
tier1.sinks.sink1.type = org.apache.flume.sink.kafka.KafkaSink
tier1.sinks.sink1.topic = sink1
tier1.sinks.sink1.brokerList = localhost:9092
tier1.sinks.sink1.channel = channel1
