Sandy Ryza commented on MAPREDUCE-5651:
---------------------------------------
Thanks Ted. A few more comments:
{code}
+ //CommonConfigurationKeys.HADOOP_SECURITY_GROUP_MAPPING,
+ placementPolicyConfig.setClass("hadoop.security.group.mapping",
{code}
Can take out the comment and just use
CommonConfigurationKeys.HADOOP_SECURITY_GROUP_MAPPING as the argument?
All mentions of "queue" should still be replaced with mentions of "pool".
{code}
+ rules.add(new QueuePlacementRule.Specified().initialize(true, null));
{code}
In simple placement rules, create param on the "specified" rule should only be
true if allow undeclared pools property is true.

> invasive in MR1 as well.
