I think we are in different points :).
The problem is when the comparation of the keys when I use Hex.decode
I emit keyValues on this way and works, but it spends double of memory
to store keys.
rowKey = Bytes.toBytes(DigestUtils.*shaHex*(pOutput.getRow()));
KeyValue kv =
new KeyValue(Bytes.toBytes(pOutput.getRow()),
family, null, ts, type, null);
If I use for rowKey:
rowKey = DigestUtils.*sha*(pOutput.getRow());
it doesn't work, I don't know why, since it's an byte array. But, I
coded some Junit test and it never deletes the keys.

Decode rowkey has timestamp.
KeyValue has timestamp field.
Do these two timestamps carry the same value ?

Hi,
I'm generating key with SHA1, as it's a hex representation after generating
the keys, I use Hex.decode to save memory since I could store them in half
space.
I have a MapReduce process which deletes some of these keys, the problem
it's that it's that when I try to delete them, but I don't get it. If I
don't do the parse to Hex, it works.
So, For example, I put the keys in SHA like
b343664e210e7a7abff3625a005e65e2b0d4616 works, but if I parse this key with
Hex.decode to *\xB3CfN!\x0Ezz\xBF\xF3bZ\x00^e\xE2\xB0\ *column=l:dd,
timestamp=1384317115000 .... it doesn't.
I have been checked the code a lot but I think it's right, plus, if I
comments the decode to Hex it works.
Any clue about it? is there any problem with I am trying to??
