             Summary: New HDFSTextWritableSerializer for HDFS Sink
                 Key: FLUME-2321
                 URL: https://issues.apache.org/jira/browse/FLUME-2321
             Project: Flume
          Issue Type: New Feature
          Components: Configuration, Sinks+Sources
    Affects Versions: v1.4.0
         Environment: Centos 6.4, Java6_u34
            Reporter: Guillermo Ortiz Fernández
            Priority: Minor


Generated a new way to save the SequenceFiles, So far, Flume has two different ways to write (Text and Writable) in HDFS, we must tell it in the configuration file like this:
colector.sinks.SinkWritable.hdfs.writeFormat = Writable.
I have created a new type TextWritable, where you can generated SequenceFile with Text as key and BytesWritable as value.
The key must be configured with in the flume.conf, for example:

colector.sinks.SinkWritable.hdfs.writeFormat = TextWritable.
colector.sinks.SinkWritable.hdfs.textWritable.keyFormat = %{file}_%{host}_hello.

When Flume generates the SequenceFile, the key will be the name of the file and the name of the host, these variables are totally configurable. If you don't define the property keyFormat the key will be the timestamp.
I have the code done. I hope to improve a little the JavaDoc, modify the documentation today and upload the patch.
