Hi, I followed the below instructions to compile the MRv2 code.
http://svn.apache.org/repos/asf/hadoop/common/branches/MR-279/mapreduce/INSTALL I start the resourcemanager and then the nodemanager and see the following error in the yarn-praveensripati-nodemanager-master.log file. 2011-07-21 19:39:54,125 INFO org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl: Connected to ResourceManager at 0.0.0.0:8025 2011-07-21 19:39:58,151 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: /0.0.0.0:8025.

Connected to 0.0.0.0. telnet 127.0.0.1 8025 Trying 127.0.0.1... Connected to 127.0.0.1. Has anyone faced a similar problem? Also, where are all the possible defaults specified (~ core-default.html) for MRv2? Thanks, Praveen
