Zhihong Ted Yu commented on HBASE-2315: --------------------------------------- @Flavio: Looking at the attached patch: {code} + public void init(FileSystem fs, Path path, Configuration conf){ {code} Parameter fs isn't used. Further, you implemented HLog.Reader and HLog.Writer. I don't see where HLog is constructed.
