@arina-ielchiieva, thank you for the review. Please check if the revised
option messages are clear.
The test failures may be due to bugs fixed in the text reader. @vvysotskyi,
check if the files in question try to use the back-slash as the escape
character. Drill's text readers are configured to use the quote character as an
escape by default, but the code did not correctly handle this case. If the file
contains the pattern `\"` or `""`, then the text reader will produce a
different result than previously.
Otherwise, please do point me to the errors and I'll track down the issues.

> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.16.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Major
> Fix For: 1.17.0
>
>
> Now that the "V3" text reader (based on the "extended vector framework) is
> fully functional, we wish to remove the prior (V2) text reader.
> Drill also contains the original, "V1" text reader that has not been used or
> supported for several years. We will remove this reader also to leave the
> code simpler and cleaner.
