Hi, I am using HBase as a source of my MapReduce jobs.
I recently found out that TableInputFormat automatically splits the input table so that each region of the table will be assigned to a single Map job. But what I want to do is to split the input table so that user-specified lines of row will be assigned to each Mapper. For example, if I set a certain parameter to 100, then each Mapper will get 100 lines from the input Table. Is there a method for this kind of operation? Or do I have to modify the getSplits() of org.apache.hadoop.hbase.mapreduce.TableInputFormatBase? Any answer or opinion will be much appreciated!! Ed
