Support for metrics aggregation module in JobTracker
----------------------------------------------------
Key: HADOOP-1918
URL: https://issues.apache.org/jira/browse/HADOOP-1918
Project: Hadoop
Issue Type: New Feature
Components: mapred
Reporter: Senthil Subramanian
JobTracker should support starting up and shutting down a generic metrics
aggregation module. We are currently thinking about plugging in a module that
gets time series data from the task trackers, aggregates it and log this data
into a global DFS so that it is analysed later (even after the map reduce
cluster is shutdown). Some of this data can also be plotted on the JobTracker
UI in realtime. This is particulary useful for analyzing data from dynamic
mapreduce cluster like the ones deployed using HOD.
