Still got the same...
I'm not sure if it is relevant to this issue but the call you added to
Fetcher.java:
job.setBoolean("mapred.speculative.execution", false);
Doesn't work. All task trackers still fetch together though I have only
3 sites in the fetchlist.
The task trackers fetch the same pages...
I have used latest build from hadoop trunk.
