trying to ingest data using flume from a website to cloudera hdfs directory

[M123]

how to deal with this error? Is the channel full?

clienta.properties

julyLog.sources= src1
julyLog.channels= chnl1
julyLog.sinks= snk1


#sources
julyLog.sources.src1.type=spooldir
julyLog.sources.src1.channels=chnl1
julyLog.sources.src1.spoolDir=/home/cloudera/sample-data/nasa_log/july
julyLog.sources.src1.inputCharset=us-ascii

#channels
julyLog.channels.chnl1.type=memory
julyLog.channels.chnl1.capacity=10000
julyLog.channels.chnl1.transactionCapacity=1000

#sink
julyLog.sinks.snk1.type = avro
julyLog.sinks.snk1.channel = chnl1
julyLog.sinks.snk1.hostname = localhost
julyLog.sinks.snk1.port = 4545

below is the error
