Hello guys,
I am launching through code (client mode) a Spark program to run in Hadoop.
If I execute on the dataset methods of the likes of show() and count() or

transformations on the columns then the mentioned methods
Hi,
I am launching through code (client mode) a Spark program to run in Hadoop.
Whenever I check the executors tab of Spark UI I always get 0 as the number

Hello,
I use Yarn client mode to submit my driver program to Hadoop, the dataset I

I hope my question does not sound weird, but could a Spark execution on
Hadoop cluster give different output than the program actually does ? I
mean by that, the execution order is messed by hadoop, or an instruction
executed twice..; ?

You can do a join or a union to combine all the dataframes to one fat
dataframe
or do a select on the columns you want to produce your transformed dataframe
Not sure if I understand the question though, If the goal is just an end

Its because you are just printing on the rdd
You can sort the df like below

or if you do not want to convert to a dataframe you can use the sort by

I don't know about the broken url. But are you running HDFS as a mesos
framework? If so is it using mesos-dns?
Then you should resolve the namenode via hdfs:///

Yea should have emphasized that. I'm running the same code on the same VM.
It's a VM with spark in standalone mode and I run the unit test directly on
that same VM. So OpenCV is working correctly on that same machine
