Ramon, You might issue an ./hadoop -list all to get the jobs and then -set-priority <id> <priority>. I know that someone from that Ocean Sync (http://www.oceansync.com) Hadoop management project is working with interacting with MapReduce jobs through a GUI, to set priorities through that, but they are still in beta.
job Command to interact with Map Reduce Jobs. Usage: hadoop job [GENERIC_OPTIONS] [-submit <job-file>] | [-status <job-id>] | [-counter <job-id> <group-name> <counter-name>] | [-kill <job-id>] | [-events <job-id> <from-event-#> <#-of-events>] | [-history [all] <jobOutputDir>] | [-list [all]] | [-kill-task <task-id>] | [-fail-task <task-id>] | [-set-priority <job-id> <priority>] ----- Original Message ----- From: WangRamon <[email protected]> To: [email protected] Cc: Sent: Sunday, November 20, 2011 4:44 AM Subject: How to manage hadoop job submit? Hi All I'm new to hadoop, I know I can use "haddop jar" to submit my M/R job, but we need to submit a lot of jobs in my real environment, there is priority requirement for each jobs, so is there any way to manage how to submit jobs? Any Java API? Or we can only use the hadoop command line with shell or python to do the job submit? Thanks Ramon
