    Description

      Currently, Rumen's TraceBuilder processes jobs in sequential manner and emits them in sorted order (based on job-id). Following are the steps :

      1. Read data from input files
      2. Parse and analyze the JobHistory data
      3. Write the data to the output file

      Steps #1 and #2 can be done in parallel. Step #3 can be made sequential (if user needs it) else can also be done in parallel.

      I could achieve ~50% speedup by simply parallelizing step#1 and step#2 (i.e output was sorted based on job-id).
