> A suggestion by Cosmin over in review of hbase-2437 (http://review.hbase.org/r/74/)  is as follows:
> {code}
> ....[b]y "writers" I mean the classes that implement the Writer interface (sync, append, etc). There's a HLog.Writer interface and the implementation is SequenceFileLogWriter that encapsulates a SequenceFile.Writer 
> We should have a common interface for HBase classes that append, sync, etc. 
> If the filesystem doesn't support append - that should be taken care in the Writer implementation that actually talks with HDFS. i.e. do it in a single class and avoid duplicating the appendSupport logic through code.
> {code}
