### SUMMARY Previously, hive csv upload only supported `,` as a delimiter. This is confusing for users because the UI allows you to specify a delimiter. This PR uses `org.apache.hadoop.hive.contrib.serde2.MultiDelimitSerDe` in hive csv upload, which supports regex delimiters. Mostly did this to support delimiters like `\s+` and `\t`, but potentially, any regex could be used. More on `MultiDelimitSerDe`: https://cwiki.apache.org/confluence/display/Hive/MultiDelimitSerDe ### TEST PLAN Tested csv + tsv uploads. ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Changes UI - [ ] Requires DB Migration. - [ ] Confirm DB Migration upgrade and downgrade tested. - [X] Introduces new feature or API - [ ] Removes existing feature or API @etr2460 @bkyryliuk @john-bodley ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
