I have tried clean and reinstall different versions of maven with no luck. Any expert knows what is going on here?

Answer 1

I came across same problem during hadoop 2.2.0 source code building. During "mvn install -DskipTests" this error came in "Hadoop Auth" Folder.
From somewhere(i dont remember from where) i came to know that there is one missing dependency in pom.xml of this Hadoop Auth folder
dependency is
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>
I added this dependency and again tried "mvn install -DskipTests". My error resolved.
You just try to add this dependency in pom.xml of "APACHE Hadoop MR1". May ur error will resolve

Answer 2

Seems like Maven compiler plugin complaining that getDelegationTokenSecretManager() method in Hadoop FSNameSystem is not accessible due to method visibility i.e. it's not public:
[ERROR] /home/xiu/myGit/hadoop2/hadoop-mr1-project/hadoop-mr1/src/test/java/org/apache/hadoop/mapreduce/security/TestTokenCache.java:[153,4] getDelegationTokenSecretManager() is not public in org.apache.hadoop.hdfs.server.namenode.FSNamesystem; cannot be accessed from outside package
[INFO] 1 error
I would suggest you to check on your Hadoop version defined in your pom.xml, and double check that the method is really accessible in the Hadoop version JavaDoc.
