Getting error while reading data from logs and writing to kafka sinks

Iam trying to read logs and write data to hdfssink and kafkasink
given below is the code

fmp.sources = logsource
fmp.sinks = kafkasink hdfssink
fmp.channels = kafkachannel hdfschannel

Describe/configure the source

fmp.sources.logsource.type = exec
fmp.sources.logsource.command = tail -F /opt/gen_logs/logs/access.log

Describe the sink

fmp.sinks.kafkasink.type = org.apache.flume.sink.kafka.KafkaSink
fmp.sinks.kafkasink.brokerlist =
fmp.sinks.kafkasink.topic =kafkadg

Use a channel which buffers events in memory

fmp.channels.kafkachannel.type = memory
fmp.channels.kafkachannel.capacity = 1000
fmp.channels.kafkachannel.transactionCapacity = 100

Bind the source and sink to the channel

fmp.sources.logsource.channels = kafkachannel hdfschannel = kafkachannel
#Describe the sink
fmp.sinks.hdfssink.type = hdfs
fmp.sinks.hdfssink.hdfs.path = hdfs://
fmp.sinks.hdfssink.hdfs.fileType = DataStream
fmp.sinks.hdfssink.hdfs.rollInterval = 120
fmp.sinks.hdfssink.hdfs.rollSize = 10485760
fmp.sinks.hdfssink.hdfs.rollCount = 30
fmp.sinks.hdfssink.hdfs.filePrefix = retail
fmp.sinks.hdfssink.hdfs.fileSuffix = .txt
fmp.sinks.hdfssink.hdfs.inUseSuffix = .tmp
fmp.sinks.hdfssink.hdfs.useLocalTimeStamp = true
#Use a channel which buffers events in file for HDFS sink
fmp.channels.hdfschannel.type = file
fmp.channels.hdfschannel.capacity = 1000
fmp.channels.hdfschannel.transactionCapacity = 100
fmp.channels.hdfschannel.checkpointInterval = 300 = hdfschannel

and iam able to see the data in hdfssinks however iam getting the below when i run the kafka consumer command

can you please let me know the issue
