hRaven Project
· hRaven collects run time data and statistics from map reduce jobs running on Hadoop clusters
and stores the collected job history in an easily queryable format. For the jobs that are run
through frameworks (Pig or Scalding/Cascading) that decompose a script or application into
a DAG of map reduce jobs for actual execution, hRaven groups job history data together by an
application construct. This will allow for easier visualization of all of the component
jobs' execution for an application and more comprehensive trending and analysis over time.
