How to fix the issue

It seems asakusa.batchc.dir is null, but the property is configures.

[marblejenka]

It is a missuse of FileExporterDescription. FileExporterDescription#getPathPrefix must supecify relative directory.

Following code cannot pass batch:compile.

public abstract class DefaultHdfsExporterDescription extends
        FileExporterDescription {
    @Override
    public String getPathPrefix() {
        return getModelType().getSimpleName() + "-*";
    }
}

Following is ok.

public abstract class DefaultHdfsExporterDescription extends
        FileExporterDescription {
    @Override
    public String getPathPrefix() {
        return "result/" + getModelType().getSimpleName() + "-*";
    }
}

please write the specification.
