Я пытаюсь использовать Flume-ng, чтобы получить 90 секунд информации журнала и поместить ее в файл в HDFS. У меня есть работа, чтобы посмотреть файл журнала через exec и tail, но он создает файл каждые 5 секунд вместо того, что я пытаюсь настроить, как каждые 90 секунд.

Мой flume.conf выглядит следующим образом:

# example.conf: A single-node Flume configuration                                                                                                                  
# Name the components on this agent                                                                                                                                
agent1.sources = source1
agent1.sinks = sink1
agent1.channels = channel1

# Describe/configure source1                                                                                                                                       
agent1.sources.source1.type = exec
agent1.sources.source1.command = tail -f /home/cloudera/LogCreator/fortune_log.log

# Describe sink1                                                                                                                                                   
agent1.sinks.sink1.type = hdfs
agent1.sinks.sink1.hdfs.path = hdfs://localhost/flume/logtest/
agent1.sinks.sink1.hdfs.filePrefix = LogCreateTest
# this parameter seems to be getting overridden                                                                                                                    
agent1.sinks.sink1.hdfs.rollInterval=90
agent1.sinks.sink1.hdfs.rollSize=0
agent1.sinks.sink1.hdfs.hdfs.rollCount = 0

# Use a channel which buffers events in memory                                                                                                                     
agent1.channels.channel1.type = memory

# Bind the source and sink to the channel                                                                                                                          
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channel = channel1

Я пытаюсь контролировать размер файла с помощью параметра -agent1.sinks.sink1.hdfs.rollInterval = 90.

Как видно по меткам времени, он создает файл примерно каждые 5 секунд или около того. Это создает много маленьких файлов.

Я хотел бы иметь возможность создавать файл на больший промежуток времени (90 секунд).
