Hi Anil, the point of getFamilyArray() is that it may return the entire buffer, but it does not *have* to. Everybody should use the new API, so that we can eventually have KeyValues (Cells) that do not have be backed by a single byte[]. (i.e. we can have KeyValues backed by separate row, family, column, value arrays)

Hi Ted, This will return entire backing bytes array just like keyValue.getBuffer()? By the documentation i thought its returning some file name : byte[] *getFamilyArray <https://hbase.apache.org/apidocs/org/apache/hadoop/hbase/Cell.html#getFamilyArray%28%29>* () Contiguous bytes composed of legal HDFS filename characters which may start at any index in the containing array. IMHO, this method name is not as intuitive as "getBuffer".
