Hi, I am trying to modify the code for data transfer of intermediate output.
In this respect, on the reduce side in getMapOuput I want to have the connection with the TaskTracker(setupSecureConnection), but then on doGet the TaskTracker to be able to delay the response back to the client. I tried with Thread.sleep(time), before setting up the response.setHeader(FROM_MAP_TASK, mapId) and the subsequent headers/content. But it seems the reducer will continue to read the headers immediately and get NULL. Do you know how can I do the reducer to wait for TaskTracker to update this information before reading it. I tried with a while loop and reading the connection.getHeaderField(...) till not null but seems it always remains in the loop :(. Probably is more a HttpServlet related problem but I am not very familiar with that. Do you have any idea how can I do it ? Thanks, Robert
