Using scala-eclipse for spark

Question

Could some please help me on how to use the scala-eclipse IDE for spark ? I came across this link - http://syndeticlogic.net/?p=311. But I am unable to follow it. I entered the command - mvn -Phadoop2 eclipse:clean eclipse:eclipse inside the spark directory after a long list of downloads it gave me some error. Please help. Thanks

Below is the error i received

Answer 1

This is because there is no profile called hadoop2 in the pom.xml. The closest matches are hadoop-2.2,hadoop-2.3 etc.

You can run the following

mvn -Phadoop-2.2 eclipse:clean eclipse:eclipse

or you may run 'mvn help:all-profiles' to list all the profiles and use one from it
