Sreekanth Ramakrishnan updated HADOOP-4854:
-------------------------------------------
Attachment: HADOOP-4854-5.patch
Attaching new patch incorporating Vivek's offline comment,
1. Corrected the forrest documentation for capacity scheduler. Previously had
copied only the description of the property, now changed the section title and
description appropriately.
> Capacity Scheduler should read the reclaim-capacity-interval config value
> from its own config file

>
> The Capacity Scheduler needs to know the time interval for checking whether
> capacity needs to be reclaimed. This is represented by the static variable
> RECLAIM_CAPACITY_INTERVAL. This value is currently read as follows:
> {code}
> RECLAIM_CAPACITY_INTERVAL =
> conf.getLong("mapred.capacity-scheduler.reclaimCapacity.interval", 5);
> {code}
> This is incorrect for the following reasons:
> * ""mapred.capacity-scheduler.reclaimCapacity.interval" is not present in any
> of the config files: hadoop-site.xml or capacity-scheduler.xml.
> * "mapred.capacity-scheduler.reclaimCapacity.interval" should be specified in
> the scheduler's config file, capacity-scheduler.xml. It should be read
> through org.apache.hadoop.mapred.CapacitySchedulerConf.
> * The Forrest documentation for the Capacity Scheduler should describe this
> setting. We should probably create a new sub-section under 'Configuration',
> titled 'Configuring properties for the Scheduler'.
