elasticsearch sincedb_路径/dev/null不起作用

我希望Logstash在没有新行的时候解析我的文件

但它不起作用：

[2017-05-09T17:28:07,523][DEBUG][logstash.inputs.file     ] each: new inode: /exports/export4hadoop_FULL.csv: old inode was ["136139751", 0, 64769], new is 
["136139747", 0, 64769]
[2017-05-09T17:28:07,523][DEBUG][logstash.inputs.file     ] :delete for /exports/export4hadoop_FULL.csv, closing file
[2017-05-09T17:28:07,525][DEBUG][logstash.inputs.file     ] _open_file: /exports/export4hadoop_FULL.csv: opening
[2017-05-09T17:28:07,526][DEBUG][logstash.inputs.file     ] /exports/export4hadoop_FULL.csv: sincedb last value 985877, cur size 985877
[2017-05-09T17:28:07,526][DEBUG][logstash.inputs.file     ] /exports/export4hadoop_FULL.csv: sincedb: seeking to 985877

我的配置文件：

input {
 file {
  path => "/exports/export4hadoop_FULL.csv"
  start_position => "beginning"
  sincedb_path => "/dev/null"
 }
}

我在主目录下没有找到任何.sincedb文件。我不知道Logstash使用的.sincedb文件在哪里

我不明白它为什么存储.sincedb，因为我指定了sincedb_path=>/dev/null

谢谢：

默认情况下用于sincedb_路径值的文件位于

LOGSTASH\u HOME\data\plugins\inputs\file

我建议您检查该文件夹中的任何文件，删除它们并重新运行测试
