Hi all,
after finish one mapreduce job, the statistics shows that the number of records
map generated is not equal to the number of records that reduce input. It says:
Map output records=150000
Reduce input records=93282
I think it is abnormal. Please give me some ideas how this happen and how to
fix it. Thanks.
