Hi all, We're experiencing a problem where a map-only job using TableInputFormat and TableOutputFormat to export data from one table into another is not reading all of the rows in the source table. That is, # map input records != # records in the table. Anyone have any clue how that could happen?
Some more detail: It appears to only happen when we are writing results to the destination table. If I comment out the lines where where data is written from the mapper (context.write), then the number of input records is correct. I verified that the rows that did not get written to the output table, so it's not just a counter problem. We aren't using any filter or anything, just a straight-up scan to try to read everything in the table. We're on hbase-0.89.20100924. Thanks, Sean
