Unable to read CSV in R from Hadoop Cluster
Hello,
I am new to big data environment, We have setup Hadoop cluster with
Zeppelin. Now trying to read csv file and getting below error. This file
have full permissions.
Error in file(file, "rt"): cannot open the connection
This is the procedure I am following.
%dep z.reset() // Add spark-csv package
z.load("com.databricks:spark-csv_2.10:1.2.0")
%spark2.r
data <- read.csv(file='test/test.csv',header=TRUE,sep='\t')
Please let me know how to fix this. Thanks

Maybe you should try via sparkly and spar2 -> this already includes the CSV
package http://spark.rstudio.com
