Hi,
I am training a RandomForest Regression Model on Spark-1.6.1 (EMR) and am
interested in how it might be best to scale it - e.g more cpus per
instances, more memory per instance, more instances etc.
I'm currently using 32 m3.xlarge instances for for a training set with 2.5

I'm having trouble with that for pyspark, yarn and graphframes. I'm using:-
pyspark --master yarn --packages graphframes:graphframes:0.1.0-spark1.5
which starts and gives me a REPL, but when I try
from graphframes import *
I get
No module names graphframes
without '--master yarn' it
A colleague found how to do this, the approach was to use a udf()

Hi, I have a RDD with MANY columns (e.g., hundreds), and most of my operation
is on columns, e.g., I need to create many intermediate variables from
different columns, what is the most efficient way to do this?
For example, if my dataRDD[Array[String]] is like below:
123, 523, 534, ..., 893
Thanks for your reply! It is what I am after.

they are generated dynamically), I need to sum up the values of these

Hi, I am new to the MLlib in Spark. Can the DecisionTree model in MLlib deal
with missing values? If so, what data structure should I use for the input?
Moreover, my data has categorical features, but the LabeledPoint requires
"double" data type, in this case what can I do?
Thank you very much.

Hi,
I'm trying to understand how a Spark Cluster behaves when the data it is
processing resides on a centralized/remote store (S3, Cassandra, DynamoDB,
RDBMS etc).
Does every node in the cluster retrieve all the data from the central store
?
