Critical Description
Hi,
In SparkR shell, I invoke:
> mydf<-read.df(sqlContext, "/home/esten/ami/usaf.json", source="json", header="false")
I have tried various filetypes (csv, txt), all fail.
in sparkR of spark 1.4 for eg.) df_1<- read.df(sqlContext, "E:/setup/spark-1.4.0-bin-hadoop2.6/spark-1.4.0-bin-hadoop2.6/examples/src/main/resources/nycflights13.csv", source = "csv")
RESPONSE: "ERROR RBackendHandler: load on 1 failed"
