> Mahout spark-shell is run with default perm gen size (64MB). Taking into account that
it depends on lots of external jars and the whole count of used Java classes is very large,
we constantly observe spontaneous corresponding OOM exceptions.
> A hot fix from our side is to modify envelope bash script (added -XX:PermSize=512m):
> {code}
> "$JAVA" $JAVA_HEAP_MAX -XX:PermSize=512m $MAHOUT_OPTS -classpath "$CLASSPATH" "org.apache.mahout.sparkbindings.shell.Main"
$@
> {code}
> Of course, more elegant solution is needed. After the applied fix, the errors had gone.
