-Re: Flume custom decorator for Rolling FileSink output bucketing
Dib, that article is in reference to flume OG(0.95), it's not relevant
to the current release.
I had looked in the past at fixing the file sink to use the same
bucketting available to the hdfs sink, but unfortunately it seemed like
it would take more than a quick fix. The PathManager currently only
works with one File at a time, and the rolling logic is connected to
that. You'd basically have to replace most of the logic, ideally reusing
the bucketing logic from the HDFS sink. As Mike said, you should
probably just use the HDFS sink with file:// unless you feel like
improving the current sink.
