Hadoop examples don't compile in Eclipse
Hi,
this is really all over, but for example, in SecondarySort.java, this line
causes a problem:
@Override
public int compare(IntPair o1, IntPair o2) {
It works beautifully in NB, but in Eclipse it was the "Override" removed,
with the following message:
Multiple markers at this line
- The method compare(SecondarySort.IntPair, SecondarySort.IntPair) of
type SecondarySort.FirstGroupingComparator must override a superclass
method
- implements
java.util.Comparator<
com.intel.hadooptraining.examples.SecondarySort.Int
Pair>.compare
Thank you,
Mark
