Ari Rabkin commented on CHUKWA-332:
-----------------------------------
Hrm. I just want to understand how we currently fix the problem that parameter
was there to address.
- Suppose I have a file, foo.txt, containing three chars "abcd".
- An adaptor looks at the file, and sends a new chunk, containing "abcd",
ending at offset 4.
- The file then rotates, and now contains "efg". What should the adaptor send?
> Remove first offset tracker from CharFileTailingAdaptorUTF8NewLineEscaped
> adaptor

> Project: Hadoop Chukwa
> Issue Type: Improvement
> Components: data collection
> Affects Versions: 0.3.0
> Environment: Redhat EL 5.1, Java 6
> Reporter: Eric Yang
> Fix For: 0.3.0
>
>
> CharFileTailingAdaptorUTF8NewLineEscaped is currently taking Starting offset
> of the file, and current streaming offset of the file. The original idea of
> using starting offset as a unique sequence tracker to track the unique record
> for the life time of the stream. However that idea didn't pan out. Hence,
> we should remove the first offset to avoid confusion. The current streaming
> offset is sufficient to start tailing file.
