Hi,
Can you please confirm that the line number 45 in ClosenessMessageWritable
is as follows:
this.previous_bitstring[i] = in.readBoolean();
If its then try the following. Hopefully it will fix your problem
@Override
public void readFields(DataInput in) throws IOException {
size=in.readInt();
previous_bitstring = new boolean[size];
for(int i=0;i<size;i++)
{
previous_bitstring[i] = DataInput.readBoolean();
}
}
