select name, count(*) from amazon where review != NULL group by name ;
Number of reduce tasks not specified. Estimated from input data size: 1
In order to change the average load for a reducer (in bytes):
In order to limit the maximum number of reducers:
In order to set a constant number of reducers:
set mapreduce.job.reduces=<number> Starting Job = job_1564815666993_0001, Tracking URL = http://aamir-VirtualBox:8088/proxy/application_1564815666993_0001/ Kill Command = /usr/local/hadoop/bin/hadoop job -kill job_1564815666993_0001
