The answer to this question is TBD. I have yet to test how it works in a loaded 
cluster. To this point, I have just verified that in
a simple test that it works. More to come soon...

> In order to guarantee that an HLog sync() flushes the data to the HDFS, we 
> will need to invoke FSDataOutputStream.sync() per HADOOP-4379.
> Currently, there is no access to the underlying FSDataOutputStream from 
> SequenceFile.Writer, as it is a package private member.
