METRON-1153 HDFS HdfsWriter never recovers from exceptions
## Contributor Comments
Added a try-catch around the actual write that will rotate the file and try
again if there's a stream closed underneath it. Added two unit tests, one that
ensures things flow through nicely to a single file with a double write and one
that ensures that things flow to two files if the channel is closed underneath
for whatever reason (done by just calling `closeOutputFile()` when outside of
the normal flow).
It's not a perfect solution, but it should alleviate any transient pain and
let us know if the problem is deeper if it keeps showing up.
Also added a missing set to a field from the constructor which probably
wasn't helping things since I happened to notice it. It's a one line change,
so it seemed excessive to create a separate PR.
