Parsing fetcher hangs oocasionally
Hi,
Our fetchers are parsing and we sometimes see the parsers stall and eventually
hang. This happens consistently during some mappers. When they are restarted
by Hadoop they're guaranteed to stall at roughly the same point, the parsers
start to timeout first and then the fetcher refuses to print its usual
progress.
I did some stack traces and all threads are blocked and most involve the
parser. I can't seem to understand the issue here so any pointers are much
appreciated. We have a useless cluster right now :)
Thanks!
