Subject Increase timeout for running PFPGrowth
Date Mon, 22 Oct 2012 17:08:38 GMT
Hi,

I am running PFP on several datasets and it works well for smaller ones (<
5GB)
However, for the larger ones, I keep getting following timeout message.

Task attempt_201210140938_0105_r_000000_0 failed to report status for 600
seconds. Killing!

Is there a way I can increase the timeout?

I even tried passing these parameter but in vain:
-D mapred.task.timeout=18000000 -D mapred.child.java.opts=-Xmx4000m

My input params are:  -s 10000 -g 1000  -tc 8  -k 50 -method mapreduce

Also, please suggest what would be the optimum value of g and k.
Number of features > million


Thanks,
Amit
