Anoop Sam John commented on HBASE-17086:
----------------------------------------
Better NOT to mention KV and KV format in Cell.. What we need to say is that
HBase uses 2 bytes to store cell's tag length. As it is going to be +ve numbers
always, we save sign bit and so max tags length = 2 * short.MAX +1 Tell the
number. So even if the return type is int, the max tags length is less than
Int.MAX value.
> Add comments to explain why Cell#getTagsLength() returns an int, rather than
> a short

> In the Cell interface, getTagsLength() returns a int
> But in the KeyValue implementation, tags length is of 2 bytes. Also in
> ExtendedCell, when explaining the KeyValue format, tags length is stated to
> be 2 bytes
> Any plan to update Cell interface to make getTagsLength() returns a short ?
