-----------------------------------
hi Satoshi Iijima:
We use the tail dir source to collect the log, the application
will archive the log in the same directory when it records the last line
info,but the flume agent may not read the last line? How can I handle it?
> Tail Dir Source leads to duplicate events on rolling the tailed file

> Key: FLUME-2777
> URL: https://issues.apache.org/jira/browse/FLUME-2777
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: 1.7
> Reporter: Johny Rufus
> Assignee: Johny Rufus
> Attachments: FLUME-2777.patch

>
> I have a simple setup, where I write 200 events to logfile1. [TailSrc is on
> the lookout for logfile* ]
> Then I rename logfile1 to logfile2.
> I create a new logfile1 and write 100 events to it.
> Typically I should see 300 events in my channel. But I see 500 events.
> I was able to trace the duplicates to ReliableTaildirEventReader.java
> updateFiles(boolean) to the way renamed files are handled , by specifying
> starting position as 0. [This starting position should be obtained from
> tf.getPosition()]
> I am attaching a proposed fix, would be great if one of you guys
> [~iijima_satoshi] / [~hshreedharan]/ [~roshan_naik] can take a look at the
> fix and validate the issue.
