I am a freshman on Hadoop. Today, I spent the whole night trying to set up a development environment for Hadoop. I encounter several problems, first is that the eclipse can't load the plugin, I changed to another version, this problem was resolved.
But now, I have one more difficult problem. I try to set up Map/Reduce Location, if everything were well, it should connect to the server and the DFS Location could list the whole file system. Sadly, it doesn't work.
I have checked to configuration several times, it should be correct.
Here is the message I get:
Error: failure to login
An internal error occured during: "Map/reduce location status updater."
