Hi all,
I don't know too much about text coding and there is one thing confusing me. I
am implementing the bloom filter in mapreduce. The output is a bit array
(implemented as byte[ ]) and the length is 2 exp 24 (that means, 2exp21 bytes).
The size of the array should be 2 mb. But when I output it like this:
output.collect(new Text(bitArray.toString()), null); the output file is only 10
bytes. The content of the output file is something like this: [...@1c695a6.
What does Text do when I generate a new Text object using the bitArray (which
is byte[ ])?
The amazing thing is, when I use Text.getBytes() to convert it back to byte[ ],
it is exactly the same as before! How does it get the 2 mb information by the
10 bytes Text object (the value of which is [...@1c695a6)?
Thanks.
-Gang
