here configuration:

agent.sources = source1 agent.channels = channel1 agent.sinks = sinks1  agent.sources.source1.type = spooldir agent.sources.source1.spooldir = /data1/forupload agent.sources.source1.channels = channel1 agent.sources.source1.basenameheader = true   agent.channels.channel1.type = file agent.channels.channel1.capacity = 1000000 agent.channels.channel1.transactioncapacity = 10000 agent.channels.channel1.checkpointdir = /data5/checkpoint agent.channels.channel1.datadirs = /data5/flumedata agent.channels.channel1.usedualcheckpoints = true agent.channels.channel1.backupcheckpointdir = /data5/backupcheckpoint agent.channels.channel1.maxfilesize = 900000000  agent.sinks.sinks1.type = hdfs agent.sinks.sinks1.hdfs.path = /user/flume agent.sinks.sinks1.hdfs.filetype = datastream agent.sinks.sinks1.channel = channel1 agent.sinks.sinks1.hdfs.fileprefix = %{basename} agent.sinks.sinks1.hdfs.filesuffix = .csv agent.sinks.sinks1.hdfs.rollinterval = 0 agent.sinks.sinks1.hdfs.rollsize = 0 agent.sinks.sinks1.hdfs.rollcount = 0

appreciate this

i think data has been sent. can check if file want send has been removed file.name.completed. if has been removed, file should sent.

however, there might data that's still in file channel, since data transmitted in batch. if size of data left less batch size, left in channel.

in order finish sending, can use kill -sigterm flume_process_id kill process. when flume receives signal, flushes data left hdfs. , file on hdfs renamed, i.e. remove .tmp suffix.
