Pass a Delete or a Put error in hbase mapreduce

Question

I am getting below Error while running mapreduce on hbase:

java.io.IOException: Pass a Delete or a Put
    at org.apache.hadoop.hbase.mapreduce.TableOutputFormat         


        

Answer 1

Got Answer for my own question. I was setting mistakenly no of reducer tasks as '0'.

 job.setNumReduceTasks(0);

So Mapper expects Put object to directly write into Hbase table.Commenting the above line solved the issue.
