Jason Lowe commented on HADOOP-11288:
-------------------------------------
Different vendors may have different goals for a default scheduler or what
schedulers they want to support. Hortonworks uses the CapacityScheduler, for
example. Again these are vendor decisions and not Apache Hadoop decisions.
If someone wants to propose changing the default scheduler in Apache Hadoop to
FairScheduler and has good reasons to do so then that's something we can
discuss on a separate JIRA. I just am pointing out the CapacityScheduler is
supported by the Apache Hadoop community and having that scheduler as the
default is not invalid.
