Hi Guys,
We have a use cases to parse XML files using Spark RDD. Got some examples to use spark xml utils as per the link.
https://github.com/databricks/spark-xml There are some examples here. However can you guys also provide some sample code for this?
Also can you please mention the how and external package can be added from spark-shell and pyspark?
We are looking for your guidance.
Thanks,
Rajdip
