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

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
million rows, 1300 c
gt; Do you extract only the stuff needed? What are the algorithm parameters?

Hi,
I'm having trouble working out how to get the number of executors set when
using sparkR.init().
If I start sparkR with
sparkR --master yarn --num-executors 6
then I get 6 executors
However, if start sparkR with
sparkR
followed by
sc <- sparkR.init(master="yarn-client",
sparkEnvir
t with sparkR.init()?

Hi,
I'm trying to write a short function that returns the last sunday of the
week of a given date, code below
def getSunday(day):
day = day.cast("date")
sun = next_day(day, "Sunday")
n = datediff(sun,day)
if (n == 7):
return day
else:
return sun
this g
My Python is not particularly good, so I'm afraid I don't understand what
that mean

Hi,
I have a DataFrame with the columns
ID,Year,Value
I'd like to create a new Column that is Value2-Value1 where the
corresponding Year2=Year-1
At the moment I am creating a new DataFrame with renamed columns and doing
DF.join(DF2, . . . .)
This looks cumbersome to me, is there abt
Got it, I needed to use the when/otherwise construct - code below
def getSunday(day):
day = day.cast("date")
sun = next_day(day, "Sunday")
n = datediff(sun,day)
x = when(n==7,day).otherwise(sun)
return x

I had problems doing this as well - I ended up using 'withColumn', it's not
particularly graceful but it worked (1.5.2 on AWS EMR)

end the last added column( in the loop) will be the added column. like in

I have a DataFrame that has a Python dict() as one of the columns. I'd like
to filter he DataFrame for those Rows that where the dict() contains a
specific value. e.g something like this:-
DF2 = DF1.filter('name' in DF1.params)
but that gives me this error
ValueError: Cannot convert column i
A colleague found how to do this, the approach was to use a udf()

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
?
thanks
