hello everybody,
i want to implement new scheduling algorithm in hadoop, rather than fifo, fair or capacity scheduler.
i find the fifoscheduler java code but i cant understand it well.
is there any guideline to help me understand this code?
how could i make hadoop to use this java code?
i already use cloudera manager and in configuration part i could choose the type of scheduler (fifo, fair or capacity), but i dont know how to use new scheduling algorithm.
please help me!
