Description

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project blur-mapred: Compilation failure
[ERROR] /home/gman/workspace/incubator-blur/blur-mapred/src/main/java/org/apache/blur/mapreduce/lib/BlurOutputFormat.java:[421,27] <anonymous org.apache.blur.mapreduce.lib.BlurOutputFormat$BlurRecordWriter$1> is not abstract and does not override abstract method getUnderlyingCounter() in org.apache.hadoop.mapreduce.Counter

Caused because of this anonymous implementation of the Counter does not have getUnderlyingCounter() implemented. Seems to only happen on some compiler versions, I can cause it on 1.6.0_45 yet seems to pass on 1.6.0_31.

Suggest implementing the method even if it does nothing.

private Counter emptyCounter() {
return new Counter() {
};
}
