Hello, I have set up an HDFS cluster by running a name node and a bunch of data nodes. I ran into a problem where the files are only stored on the node that uses the hdfs command and was told that this is because I do not have a job tracker and task nodes set up.
However, the documentation for 2.2.0 does not mention any of these (at least not this page: http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/ClusterSetup.html). I browsed some of the earlier docs and they do mention job tracker nodes etc. So, for 2.2.0 - what is the way to set this up? Do I need a separate machine to be the "job tracker"? Did this job tracker node change its name to something else in the current docs? Thanks, Ognen
