What is anybody else seeing for timeout percentages on large fetches?
We are running a 1M page crawl and seeing about a 10% timeout rate on
a 2Mbps line running about 165 fetchers I think. We have the
fetcher.threads.fetch set to 3 but have 55 map tasks as a default on a
11 node cluster. If I am not mistaken this works out to 165 fetchers.
It is running about 16 pages / second with about 10% timeout and I
didn't know if that would be due to my settings pretty much pegging
the available bandwidth or the websites I am crawling being down or
non-responsive. 10% seemed a little high to be downed or
non-responding sites.
I'm getting these symptoms when the total number of threads is too high
for available bandwidth.
