Subject Running Giraph 1.1 on Hadoop 2.7.2
Date Thu, 03 Mar 2016 21:46:06 GMT

I am a giraph newbie & have read how giraph works but I have a couple of

1. If a machine has too much work to do, is it possible to migrate work to
another machine for faster computation? (or is this handled by partitions
from the master)

(Plz view the diagram below)
2. i. How are the number of partitions decided?
ii. What kind of Statistics are stored, how do they help the master to
choose the number of partitions for the next superstep?
iii. These statistics are in memory (because they cannot be to the disk),
am I correct?
