Hi,
I'm running a Giraph PageRank job. I tried with 8GB input text data
over 10 nodes (each has 4 core, 4 disks, and 12GB physical memory), that
is 800MB input-data/machine.However, Giraph job fails because of high
GC costs and Out-of-Memory exception.
Do I set some special things

Here are some ideas you might want to try:

I.e. Here's a setting to get 10 GB of heap and use a smaller stack (64k)
for the threads.
-Dmapred.child.java.opts="-Xms10g -Xmx10g -Xss64k"
Also, you
