I have setup my two nodes conf as described by M. G. Noll
The data node has datanode & tasktracker running (jps command shows them),
which means start-dfs.sh and start-mapred.sh worked fine.
I can also shut them down gracefully.
However in the WEB UI I only see one node for the DFS
Live Node : 1
Dead Node : 0
Same thing on the MapRed WEB interface.
Datanode logs on slave are just empty.
Did check the network settings both nodes have access to each other on
Did make sure namespaceID are the same (
I did try to put data in the DFS worked but no data seemed to arrive in the
Also tried a small MapRed only master node has been actually working, but
that could be because there is only data in the master. Right ?
