Guillermo Ortiz Fernández created FLUME-2321:
------------------------------------------------
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.
