Hi !
I have setup hadoop0.20.2 on eclipse Helios and able to run the Example
wordcount using ExampleDriver class as mentioned by Faraz in
http://lucene.472066.n3.nabble.com/HELP-configuring-hadoop-on-ECLIPSE-td1086829.html#a2241534
Two questions ?
1. I am unable to see the jobtracker & others in browser at http addr
mentioned in mapred- default.xml. i have not edited any site.xml files.
I have tried to edit site.xml files as per Michael noll site but that
didn't help.
2.Capacity Scheduler :I see the capacity -*- jar in lib folder. I have
modified mapred-site.xml and capacity-scheduler.xml as required. How do i
run some application jobs by submitting a job to a queue in this case ?
I have tried to run:
Program & Args as : wordcount -Dmapred.job.queue.name=myqueue1
input_file_loc output_file_loc
But i get error :
Exception in thread "main" java.lang.Error: Unresolved compilation
problems:
ProgramDriver cannot be resolved to a type
ProgramDriver cannot be resolved to a type
DistributedPentomino cannot be resolved to a type
.................
Thanks,
Arun
