I'm using HBase with MapReduce to load a lot of data, so I have decide to
do it with bulk load.
I parse my keys with SHA1, but when I try to load them, I got this
exception.
java.io.IOException: Added a key not lexically larger than previous
key=\x00(6e9e59f36a7ec2ac54635b2d353e53e677839046\x01l\x00\x00\x01E\xB3>\xC9\xC7\x0E,
lastkey=\x00(b313a9f1f57c8a07c81dc3221c6151cf3637506a\x01l\x00\x00\x01E\xAE\x18k\x87\x0E

I work with HBase 0.94.6. I have been loking for if I could define any
reducer, since, I have defined no one. I have read something about
KeyValueSortReducer but, I don'tknow if there's something that extends
TableReducer or I'm lookging for a wrong way.
