------------------------------
Hi [~klonikar],
Thanks for your interest. When I did the tests, I only checked whether spark
can support the various hive file formats. I didn't dive into the code details
either.
To answer your question, my guess is that both hive table and spark RDD are
nothing but a bunch of hadoop files at the very bottom. How the file is read is
the job of specific RecordReader/SerDe of that file format. At the higher level
both hive table and RDD are row-wise. [~xuefuz] please correct me if I
misunderstand.
Although I didn't find any issue during this JIRA, please feel free to report
any problems you found. Thanks!
