> Exporting from Parquet to CSV - commas in strings are not escaped
> -----------------------------------------------------------------
>
> Key: DRILL-4788
> URL: https://issues.apache.org/jira/browse/DRILL-4788
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Affects Versions: 1.6.0
> Environment: Linux
> Reporter: Richard Patching
> Priority: Major
> Labels: csv, csvparser, export
> Fix For: 1.17.0
>
>
> When exporting data from Parquet to CSV, if there is a column which contains
> a comma, the text after the comma gets put into the next column instead of
> being escaped.
> The only work around is to do REGEXP_REPLACE(COLUMN[0], ',',' ') which
> replaced the comma in the string with a blank space. This is not ideal in
> terms of keeping a true accurate record of the data we receive.
