Eric Payne commented on MAPREDUCE-2789:
---------------------------------------
Sorry about the last comment.
I would like to propose that we reformat the output of {{bin/mapred job
-list}}. In 0.20, the output has a lot of text surrounding the SchedulingInfo
metrics. In 0.23, we will be adding mroe more metrics, and I think that the
output should have a more tabular format rather than string based.
Here's what I'm talking about:
0.20 Formatted output of {{bin/mapred job -list}}:
{noformat}
JobId State StartTime UserName Priority
SchedulingInfo
job_201106250538_52673 2 1316470290916 gmon NORMAL 0
running map tasks using 0 map slots.
0
additional slots reserved.
0
running reduce tasks using 0 reduce slots.
0
additional slots reserved.
{noformat}
Current 0.23 Formatted output of {{bin/mapred job -list}}:
{noformat}
JobId State StartTime UserName Queue
Priority SchedulingInfo
job_1316617280602_0001 SUCCEEDED 1316623818863 ericp default NORMAL
10.74.90.193:19888/yarn/job/job_1316617280602_1_1
{noformat}

Jira MAPREDUCE-2790 (which is related to this jira) is proposing to
# Add a column header named {{AMInfo}}
# move the value currently contained in {{SchedulerInfo}} to the new {{AMInfo}}
column
# Put a string into the {{SchedulerInfo}} field similar to that which existed
in 0.20.
I think that the {{SchedulerInfo}} field is already kind of messy with so much
verbage surrounding the metrics. And, as we add new fields to this output, it
makes it even more confusing.
So, here is my proposal for a modified format:
{noformat}
User Map Reduce
Reserved Reserved
JobId State StartTime Name Queue Priority Tasks Tasks
Containers Containers Resources Resources AMInfo
job_131646_0001 RUNNING 1316467125 ericp default NORMAL 3 1 4
1 4M 1M 10.74.90.193:19888/yarn/job/job_131646_1_1
job_135790_0002 RUNNING 1316813579 admin priqueu NORMAL 7 2 9
3 7M 3M 10.74.90.193:19888/yarn/job/job_135790_1_1
{noformat}
Please let me know what you think.
