Hi All, I am using Mapreduce API to read Hbase Table, based on some scan operation in mapper and putting the data to a file in reducer. I am using Hbase Version "Version 0.94.5.23".
*Problem:* Now in my job, my mapper output a key as text and value as text, but my reducer output key as text and value as nullwritable, but it seems *hbase mapreduce api dont consider reducer*, and outputs both key and value as text. Moreover if the same key comes twice, it goes to the file twice, even if my reducer want to log it only once. Could anybody help me with this problem?
