As a standalone utility, Job Analyzer provides a quick way to analyze the reduce load of a previously run job.
To run Job Analyzer as a standalone utility:
Log in to the server where you will run Job Analyzer.
Locate the output logs from the job to analyze:
Set oracle.hadoop.balancer.application_id to the job ID of the job you want to analyze.
You can obtain the job ID from the YARN Resource Manager web interface. Click the application ID of a job, and then click Tracking URL. The job ID typically begins with "job_".
Alternately, if you already ran Perfect Balance or Job Analyzer on this job, you can read the job ID from the application_id file generated by Perfect Balance in its report directory (outdir/_balancer by default).
Run the Job Analyzer utility as described in "Job Analyzer Utility Syntax."
