Meter/wordcount of files on the number of words:
Hadoop jar hadoop - graphs - examples - against 2.4.1. Jar wordcount wordcount2/output2
Come out with such information (part), how to see the statistics on the number of words is correct? The results of statistics is which?

The Map output materialized bytes=61
Input the split bytes=101
Combine the input records=5
Combine the output records=4
Reduce input groups=4
Reduce the shuffle bytes=61
Reduce the input records=4
Reduce the output records=4
Spilled Records=8

Know, can use the hadoop fs - cat/output/part - r - 00000 to check the statistics on the number of all kinds of words
