How to convert .txt / .csv file to ORC format

Question

For some requirement I want to convert text file(delimited) to ORC(Optimized Row Columnar) format. As I have to run it in regular intervals

Answer 1

You can insert text data into a orc table by such command:

insert overwrite table orcTable select * from textTable;

The first table is orcTable is created by the following command:

create table orcTable(name string, city string) stored as orc;

And the textTable is as the same structure as orcTable.
