> A special serializer for HDFS Sink was added to Flume a while back, but it's not documented.  This serializer is useful when the source is any type of syslog source.
> Without specifying the serializer, the timestamp and host are not logged to the file with the event information, which is pretty useless without the timestamp and hosts.
> The serializer can be configured on an hdfs sink like so:
> agent1.sinks.k1.serializer=HEADER_AND_TEXT
> Without this serializer specified you get (for example):
> adclient[12112]: INFO  <bg:krb5.conf> daemon.main Start trusted domain discovery
> as an event.  
> When you specify the serializer, the same event looks like this:
> {timestamp=1364380838000, Severity=6, host=myhostname, Facility=4} adclient[12112]: INFO  <bg:krb5.conf> daemon.main Start trusted domain discovery
> Which is much more useful.
