Hi Franco Maria,
Try with:
MAP_MEMORY=1500
JAVA_CHILD_OPTS=-Xmx1G
-Dmapred.job.map.memory.mb="${MAP_MEMORY}" \
-Dmapred.map.child.java.opts="${JAVA_CHILD_OPTS}" \
Cheers,

Hi all,
I am running the PageRank code on single machine hadoop installation.
In particular, I am running the code using four workers on a graph of
100.000 nodes. I am getting this exception:
