Re: Tools for extracting data from hadoop logs

I think you want to analyze hadoop job logs in jobtracker history folder?
These logs are in a centralized folder and don't need tools like flume or
scribe to gather them.
I used to write a simple python script to parse those log files, and
generate csv/json reports, basically you can use it to get execution time,
counter, status of job, taks, attempts, maybe you can modify it to meet you
