Running Apache 1.0.2 ~12 datanodes Ran FSCK / -> OK, before, everything running as expected.
Started trying to use a script to assign nodes to racks, which required several stop-dfs.sh / start-dfs.sh cycles. (with some stop-all.sh / start-all.sh too if that matters. Got past errors in script and data file, but dfsadmin -report still showed all assigned to default rack. I tried replacing one system name in the rack mapping file with it's IP address. At this point the NN failed to start up. So I commented out the topology.script.file.name property statements in hdfs-site.xml NN still fails to start; trace below indicating EOF Exception, but I don't know what file it can't read. As always your patience with a noob appreciated; any suggestions to get started again? (I can forget about the rack assignment for now) Thanks.
