Problem with sending message from flume to kafka - apache-kafka

Question

I have two hosts in two different VMs,
i have flume on a Centos 7 host and kafka on cloudera host.
So i connected the two of them and make kafka in the cloudera host as sink in flume as represent the code bellow :
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = spooldir
a1.sources.r1.spoolDir = /root/Bureau/V1/outputCV
a1.sources.r1.fileHeader = true
a1.sources.r1.interceptors = timestampInterceptor
a1.sources.r1.interceptors.timestampInterceptor.type = timestamp
# Describe the sink
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.topic = flume-topic
a1.sinks.k1.kafka.bootstrap.servers =
192.168.5.129:9090,192.168.5.129:9091,192.168.5.129:9092
a1.sinks.k1.kafka.flumeBatchSize = 20
a1.sinks.k1.kafka.producer.acks = 1
a1.sinks.k1.kafka.producer.linger.ms = 1
a1.sinks.k1.kafka.producer.compression.type = snappy
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
I got this error when flume try to send messages to kafka :
[root#localhost V1]# /root/flume/bin/flume-ng agent --name a1 --conf-file /root/Bureau/V1/flumeconf/flumetest.conf
