Review request for Flume.
Changes
-------
Updating description.
Description (updated)
-------
This patch adds a spooling directory based source. The idea is that a user can
have a spool directory where files are deposited for ingestion into flume. Once
ingested, the files are clearly renamed and the implementation guarantees
at-least-once delivery semantics similar to those achieved within flume itself,
even across failures and restarts of the JVM running the code.
This helps fill the gap for people who want a way to get reliable delivery of
events into flume, but don't want to directly write their application against
the flume API. They can simply drop log files off in a spooldir and let flume
ingest asynchronously (using some shell scripts or other automated process).
Unlike the prior iteration, this patch implements a first-class source. It also
extends the avro client to support spooling in a similar manner.
This addresses bug FlUME-1425.

Testing
-------
Extensive unit tests and I also built and played with this using a stub flume
agent. If you look at the JIRA I have a configuration file for an agent that
will print out Avro events to the command line - that's helpful when testing
this.
Thanks,
Patrick Wendell
