Parallel CSV imports result in: "CSV lines(s) must not be null" error

[sidohaakma]

Describe the bug
When you run large CSV import jobs in parallel sometimes the error "CSV lines(s) must not be null" is thrown. When you run the jobs sequentially it does not happen.

To Reproduce
Steps to reproduce the behavior:

1. Create 2 tables in Opal (only the dictionary)
2. Import CSV files larger than 10000 rows
3. Import a second CSV file larger than 10000 rows
4. A "CSV lines(s) must not be null" error is thrown

Expected behavior
The import jobs successfully imports the data.

Which CSV importer do you use: the built-in one or the one that is based on R?

[ymarcon]

Ah ok I see in log that it is the built-in CSV. Will try to reproduce.
