Is preemption for the capacity scheduler available in 2.3.0?
I am a little confused on capacity scheduler preemption support. Based on capacity scheduler document, preemption is not supported yet.
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-18.104.22.168/ds_Hadoop/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html. However, I read from hortonworks’s presentation at http://www.slideshare.net/hortonworks/yarn-big-datacampla, it seems preemption is supported. Is it support or not?
I like to use capacity scheduler but without preemption support, it is hard to guarantee availability of resource for high priority job.
