Hi,

I have a code fragment in which I am using a static code block to initialize a variable.

public static class JoinMap extends 
            Mapper<IntWritable, MbrWritable, LongWritable, IntWritable> {
        .......
        public static RTree rt = null;
        static {
            String rtreeFileName = "R.rtree";
            rt = new RTree(rtreeFileName);
        }
        public void map(IntWritable key, MbrWritable mbr,Context context)
                throws IOException, InterruptedException {
                            .........               
                List elements = rt.overlaps(mbr.getRect());
                .......

        }

    }

My problem is that the variable rt in the above code fragment is not getting initialised. Can anybody suggest a fix or an alternate way to initialise the variable. I don't want to initialise it inside my map function since that slows down the entire process.
