Lars Hofhansl commented on HBASE-10531:
---------------------------------------
{code}
Cell right = KeyValue.createKeyValueFromKey(current.keyBuffer, 0,
current.keyLength);
{code}
Eventually we should be able to have new implementation of Cell where we just
the row/family/column/ts without copying anything (actually that is part of the
goal).
Until do that, though, it seems better to stay using keyBuffer directly,
otherwise we'll add yet another copy to an already expensive part of the
scanning.

> Currently the byte[] key passed to HFileScanner.seekTo and
> HFileScanner.reseekTo, is a combination of row, cf, qual, type and ts. And
> the caller forms this by using kv.getBuffer, which is actually deprecated.
> So see how this can be achieved considering kv.getBuffer is removed.
