Hi Hadoop Champs,

I am facing this issue while trying to configur= e Eclipse with Map-Reduce.

Exception in thread "main" = java.lang.Error: Unresolved compilation problems:
=A0=A0=A0 The method = setInputFormat(Class<? extends InputFormat>) in the type JobConf is n= ot applicable for the arguments (Class<TextInputFormat>)
=A0=A0=A0 The method setOutputFormat(Class<? extends OutputFormat>) i= n the type JobConf is not applicable for the arguments (Class<TextOutput= Format>)
=A0=A0=A0 The method setInputPaths(Job, String) in the type = FileInputFormat is not applicable for the arguments (JobConf, Path)
=A0=A0=A0 The method setOutputPath(Job, Path) in the type FileOutputFormat = is not applicable for the arguments (JobConf, Path)

=A0=A0=A0 at Tes= tDriver.main(TestDriver.java:30)

I have these classes= and flow pattern.
