The patch looks nice to me. Of course, your work is useful.
It would be great if this feature is applied to DelimitedTextFile too because DelimitedTextFile is new replacement to CSVFile. DelimitedTextFile's performance is really great. According to some benchmark result, it can parse more than 500MB CSV data sets per second. It also can boost up query response times in many cases, especially I/O intensive workloads.
I think that the work for DelimitedTextFile does not need to be done in this issue. We can do in another jira.
Anyway, could you fix some test failure? It still has one test failure.
