Robert Joseph Evans commented on YARN-50:
-----------------------------------------
loading of mapred-default.xml and mapred-site.xml is done on demand. It is not
enough to have them on the class path. Someone needs to call
org.apache.hadoop.mapreduce.util.ConfigUtil.loadResources(). There are a
number of classes that do this, but most of them are related to running
map/reduce jobs, like Cluster, Job, JobClient, and JobConf. We had a very
similar problem with the RM not loading the HDFS configs and causing HDFS
tokens to not be renewed. We fixed it by having the HDFS renewer explicitly
load the HDFS configs, and I think we want to do the same thing here. When the
history server has a renewer it should explicitly call into
ConfigUtil.loadResources() just like JobConf or Cluster do.
> Implement renewal / cancellation of Delegation Tokens
