Hadoop File system performance counters

abhishek sharma
Hi,

What do the following two File Sytem counters associated with a job
(and printed at the end of a job's execution) represent?

FILE_BYTES_READ and FILE_BYTES_WRITTEN

How are they different from the HDFS_BYTES_READ and HDFS_BYTES_WRITTEN?

Thanks,
Abhishek
