Hi ,
I am trying to read a csv file in the following way :
val csvData = sc.textFile("file:///tmp/sample.csv")
csvData.collect().length
This works file on spark-shell but when I try to do spark-submit of the jar,
I get the following exceptions :
java.lang.IllegalStateException: unread block data
java.io.ObjectInputStream$BlockDataInputStream.setBlockDataMode(ObjectInputStream.java:2420)
java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1380)
java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1989)
