Hi Revanth, How do you register the custom codec? Do you get any errors? Have you tried using a pre-existing codec? It would be helpful if you can give more information. Dinesh On Saturday, April 14, 2018, 7:29:30 PM PDT, Revanth Reddy <revanthkuma...@gmail.com> wrote:
Hi Team , I want to write a custom cassandra codec and i want to use that codec in my spark application while reading the data from cassandra table . Basically the custom codecs are used to convert one column type to another while reading from cassandra. for example i have a timestamp column in cassandra table ,but i want to read it as long and save as parquet file to HDFS , then this cutom codecs will be usefull instead of doing an additional transformation in the spark code.
