Ravi Gummadi commented on MAPREDUCE-2400:
-----------------------------------------
In MR-279 branch, this JIRA added setting of config property
mapreduce.framework.name to "yarn". This is causing MiniMRCluster related
testcases to get NPE because configuration in MiniMRCluster needs to set this
property to classic for JT,etc to work. NPE is because ClientProtocol in
Cluster.java is null because mapreduce.framework.name is "yarn".
Vinod, Would you please add this fix (code change in
MiniMRCluster.createJobConf(JobConf)) of setting this property to "classic" as
part of your bugfix patch ?
