in tom white's book, Hadoop, The Definitive Guide, in the second edition,
on page 99, he shows how to compare the raw bytes of a key with Text
fields. he shows an example like the following.
int firstL1 = WritableUtils.decodeVIntSize(b1[s1]) + readVInt(b1, s1);
int firstL2 = WritableUtils.decodeVI
A text object is written out as a vint representing the number of bytes and
then the byte array contents of the text object
Because a vintage can be between 1-5 bytes in length, the decodeVIntSize
method examines the first byte of the vint to work out how many bytes to
skip over before the text by
chris,
thanks. i see now.
internally, i use String instead of Text and so I use
WritableUtils.writeString(...) and not Text.write(...). in the latter
method, i see that it calls WritableUtils.writeVInt(...) before
out.write(byte[], start, length).
tom white uses Text internally to represent stri
