Hadoop JobTracker GUI (port 50030) job counters have incorrect values
Last modified: 2014-03-03 11:31:31 EST
Description of problem:
Hadoop JobTracker GUI (port 50030) is reporting incorrect job counter values for some counters. Some examples include:
"SPLIT_RAW_BYTES" is a negative number (this is a count and should be a positive integer)
"Bytes Read" is zero for jobs that are reading data.
"Rack-local map tasks" is reported however, Hadoop-glusterfs does not have rack awareness.
"Data-local map tasks" is not reported
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Run a mapreduce job
2.open a web brower port 50030 for node running your jobtracker
3. under "Completed Jobs" click on a jobid and view the job counters for that job.

This is a counters issue. We should have full counter support with the new plugin rearchitecture. I suspect, this is no longer an issue.
Fixed in latest redesign using the (Raw)LocalFileSystem.
