HDPCD:Spark

[#1]

Hi,

I have a question regarding the exam. If the question does not specify the output format (json, parquet, etc..), does it mean I can use any of the available options in spark? For example, would the output (which I will export via my Spark code) in hdfs "part0000-.....gz.parquet" be valid (assuming the data inside complies with the question conditions/criteria).

Also, may I used DataFrames & Spark SQL to process the datasets, instead of plain RDD if the question does not specify that as well?

Thanks

If the question does not state a format, then use text. However, the tasks are fairly specific as to how the data should be output, so make sure you follow the task instructions carefully.
