import hadoop source code to intellij

I want to import hadoop source code 2.7.2 in intellij IDe . I do like this : file -existing project - maven -choose pom.xml in hadoop 2.7.2. source file -after import I get error in maven project view .

does any body know what to do? I read Import Maven dependencies in IntelliJ IDEA .but it did not work . thank


I think there's a problem with PSI caches.

So try File -> Invalidate Caches/Restart..

NOTE: This one will wipe out any shelved changes.

I assume you won't have that problem because you are still in importing project.

Need Your Help
