I believe that your command line interpreter does not subtitude the wildcard correctly (mine does neither). So directly talking to the jars seems to fix this: javac -cp /usr/local/hama/hama-core-0.5.0.jar:/usr/local/hadoop/hadoop-core-1.0.1.jar:/usr/local/hama/hama-graph-0.5.0.jar: SSSP.java
will be compiled to the SSSP.class and their subclasses. Hope this also fixes it for you ;) 2012/8/15 Chui-Hui Chiu <[email protected]> > Hello, > > I tried to compile an official example, SSSP, with the following command. > javac -classpath "<Hama root>/*.jar:<Hadoop root>/*.jar" <Hama source > root>/examples/src/main/java/org/apache/hama/examples/SSSP.java > > This is one of the 76 similar error messages. > <Hama source > root>/examples/src/main/java/org/apache/hama/examples/SSSP.java:23: package > org.apache.hadoop.fs does not exist > import org.apache.hadoop.fs.Path; > > The pre-built packages seem to be not properly imported.
