Made changes to the SparkContext to have a DynamicVariable for setting local properties that can be passed down the stack. Added an implementation of the fair scheduler
Changed the name of the system property to set the allocation xml
Updated/Refactored the Fair Task Scheduler. It does not inherit ClusterScheduler anymore. Rather, ClusterScheduler internally uses TaskSetQueuesManager that handles the scheduling of taskset queues. This is the class that should be extended to support other scheduling policies
Cleaned up the code
Removed some commented code
refactor fair scheduler implementation
1.Chage "pool" properties to be the memeber of ActiveJob
2.Abstract the Schedulable of Pool and TaskSetManager
3.Abstract the FIFO and FS comparator algorithm
4.Miscellaneous changing of class define and construction
Just update typo and comments
upgraded sbt version, sbt plugins and some library dependencies to latest stable version
added SPARK_WORKER_INSTANCES : allows spawning multiple worker instances/processes on every slave machine
spark instance number must be present in log filename to prevent multiple workers from overriding each other's logs
Bump development version to 0.8.0
1.remove redundant spacing in source code
2.replace get/set functions with val and var defination
change some typo and some spacing
