Hadoop 2.0.5 YARN Single Node Cluster Pseudo-Distributed Operation
Hi
I have some basic Getting Started Questions.
1. Is there a pseudo-distrubution configuration for Hadoop v2 similar to
what we had in V1, where the NameNodes, Data nodes are seperate processes
http://hadoop.apache.org/docs/stable/single_node_setup.html
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
2. In the Yarn Single Cluster Configuration, we don't start the Name
Node/Data Nodes etc as explained in the the document.
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
Do I need to configure the hdfs-site.xml and start the namenode and data
nodes?
thanks,
Rajesh

Yes, unfortunately the docs seem to have missed this. Can you pls open a jira? It's very similar to HDFS in hadoop-1.x.
