-------------------------------------

Alternatively, we could just walog to hdfs now that append works.

> If the disk is full for a Logger it will kill itself quickly. Instead we should have
it fail into a 'read-only' mode, that way tservers can still do log recovery based on the
data it has. It needs to be treated in such a way that tservers won't rely on it to log their
new data, but can be used to recover older data.
