Hi,
I am trying to run below code to read file as a dataframe onto a Stream (for
Spark Streaming) developed via Eclipse IDE, defining schemas appropriately, by
running thin jar on server and am getting error below. Tried out suggestions
from researching on internet based on "spark.read.option.schema.csv" similar
errors with no success.
Am thinking this can be a bug as the changes might not have been done for
readStream option? Has anybody encountered similar issue for Spark Streaming?
Looking forward to hear your response(s)!
ThanksSrabasti Banerjee
