STORM-595 Added support for serialization to SequenceFileBolt
Added support for org.apache.hadoop.io.serializer.Serialization to the
SequenceFileBolt. This commit breaks the 0.9.3 API by changing Writable to
Object in SequenceFormat.

Added support for serialization to SequenceFileBolt
Added support for org.apache.hadoop.io.serializer.Serialization to the
SequenceFileBolt. The new SerializableSequenceFormat interface allows
serialization systems like Avro to be plugged into the SequenceFileBolt.

> Key: STORM-595
> URL: https://issues.apache.org/jira/browse/STORM-595
> Project: Apache Storm
> Issue Type: Bug
> Affects Versions: 0.9.3
> Reporter: Mike Thomsen
> Assignee: Mike Thomsen
> Priority: Minor
>
> The current SequenceFormat interface requires that key() and value() return a
> class that implements Writable. This limitation makes it impossible to use
> object serialization systems like Avro or even Java serialization with the
> HDFS SequenceFileBolt.
> Proposed solution: change SequenceFormat so that key() and value() return an
> Object, not a Writable. This would keep existing functionality for those
> implementing Writable support while allowing serialization support for those
> of us that need it.
