My java eclipse hadoop map reduce program is displaying an error unable to locate the input file. I had copied the files to hadoop directory via terminal using hadoop commands. I can see the files in java eclipse dfs location. And also using the command hadoop dfs -ls in terminal. When i created a normal folder (not hdfs) then the problem get solved. But then program is accesing the file from local file system. I had installed hadoop 1.2.1 on redhat server 32 bit, using java eclipse luna, i had already included hadoop plugins and external jar files from the hadoop library. Input and output path are given through run time arguments

First of all,Hadoop eclipse plugins doesn't have great reliability. I had the same problem when using the plugin with the Eclipse Luna. But that compatibility issue got solved when i used Eclipse Juno. And there is no suitable plugin available for Hadoop 2.x versions. You can use the tool Maven to manage all the Hadoop dependencies just like Hadoop eclipse plugin except that you should run the Job from the terminal.

Accept my answer if it fits your case. :)
