RowSimilarity error

[Pat Ferrel]

I've been trying to get a rowsimilarity job to complete. It continues to 
timeout on a RowSimilarityJob-CooccurrencesMapper-Reducer task so I've 
upped the timeout to 30 minutes now. There are no errors in the logs 
that I can see and no other task I've tried is acting like this. Is this 
expected? Shouldn't the task check in more often?

It's doing 34,000 docs with 40 sim docs each on 8 cores so it is a bit 
slow anyway, still I shouldn't have to turn up the timeout so high 
should I?
