> HDFSEventSink causes *.snappy file to be created in HDFS even when snappy

> If I use HDFSEventSink and specify the codec to be snappy, then the sink
> writes data to HDFS with the ".snappy" extension... but the content of those
> HDFS files is not in snappy format when the snappy libs aren't found. The log
> files mention this:
> 2012-05-11 19:38:49,868 WARN util.NativeCodeLoader: Unable to load
> native-hadoop library for your platform... using builtin-java classes where
> applicable
> 2012-05-11 19:38:49,868 WARN snappy.LoadSnappy: Snappy native library
> not loaded
> ...and I think it should be an error rather than a warning... the sink
> shouldn't write data at all to HDFS if it's not in the format expected by the
> config file (ie, not compressed with snappy). The config file I used is:
> agent.channels = c1
> agent.sources = r1
> agent.sinks = k1
> #
> agent.channels.c1.type = MEMORY
> #
> agent.sources.r1.channels = c1
> agent.sources.r1.type = SEQ
> #
> agent.sinks.k1.channel = c1
> agent.sinks.k1.type = LOGGER
> #
> agent.sinks.k1.channel = c1
> agent.sinks.k1.type = HDFS
> agent.sinks.k1.hdfs.path = hdfs://<host>:<port>:<path>
> agent.sinks.k1.hdfs.fileType = DataStream
> agent.sinks.k1.hdfs.codeC = SnappyCodec
