Make SocketTeeWriter work in a single stage pipleine
----------------------------------------------------

                 Key: CHUKWA-409
                 URL: https://issues.apache.org/jira/browse/CHUKWA-409
             Project: Hadoop Chukwa
          Issue Type: Bug
          Components: data collection
    Affects Versions: 0.3.0
            Reporter: thushara wijeratna
            Priority: Minor


I wanted to use SocketTeeWriter without going through the steps of
writing to HDFS.
It seems that PipelineStageWriter is designed to have any number of
PipeLineable writers, optionally followed by a SeqFileWriter.
So I changed my collector config :

 <property>
   <name>chukwaCollector.writerClass</name>
   <value>org.apache.hadoop.chukwa.datacollection.writer.PipelineStageWriter</value>
 </property>

 <property>
   <name>chukwaCollector.pipeline</name>
   <value>org.apache.hadoop.chukwa.datacollection.writer.SocketTeeWriter</value>
 </property>

After doing one minor change to SocketTeeWriter, I could get this to
work. The advantage is that now I do not need to set up HDFS.
