Subject Re: getting hadoop job status/progress outside of hadoop
Date Tue, 17 Jun 2008 17:39:17 GMT
try this:

hadoop job  -Dmapred.job.tracker=hermitage:9001 -status

(and replace my job id with the one you want to track):
hadoop job  -Dmapred.job.tracker=hermitage:9001 -status

Job: job_200806160820_0430
file: /data/tmp/hadoop/mapred/system/job_200806160820_0430/job.xml
tracking URL:
map() completion: 1.0
reduce() completion: 0.20370372
