Hi there:
This is tremendous interesting for me as well.
I started with spark in local mode , assuming it will be a complete disaster
regarding performance.
I’ve been able to reach hdfs files hosted in a remote data lake from de
spark-shell.
My next step is that you are describing. The idea is that workers must be as
close as possible to data nodes because the best network is that doesn’t exists
( lets them to be in the very same node to reduce communication costs)
After that, It would be nice form me that zeppelin will allow me no to pain
with this error that I’m still dealing with:
%spark
val data = Array(1, 2, 3, 4, 5)
val path2file="/home/zeppelin/Downloads/bank.csv"
val cotizFile = sc.textFile(path2file,2)
data: Array[Int] = Array(1, 2, 3, 4, 5)
path2file: String = /home/zeppelin/Downloads/bank.csv
com.fasterxml.jackson.databind.JsonMappingException: Could not find creator
property with name 'id' (in class org.apache.spark.rdd.RDDOperationScope)
at [Source: {"id":"24","name":"textFile"}; line: 1, column: 1]
at
com.fasterxml.jackson.databind.JsonMappingException.from(JsonMappingException.java:148)
at
com.fasterxml.jackson.databind.DeserializationContext.mappingException(DeserializationContext.java:843)
So, please follow on your path. Perhaps configuring correctly my remote
connection, I will be able to avoid my “stopper”
Thanks for your inputs. I’ll be looking forward your next messages
Saludos cordiales / Kind regards

Asunto: Re: Configure Zeppelin to connect to remote Hadoop
So, I have to use the IP address of the remote hadoop node?
How about the hive configs?

You mean this?
master spark://master:7077
Then spark will connect to hdfs
