-------------------------------
Summary: Drill Query fails when the escape character(which is part
of the data) is just before the quote
Key: DRILL-8496
URL: https://issues.apache.org/jira/browse/DRILL-8496
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.21.1
Reporter: achyut09
I have the following csv-
{{}}
{code:java}
"id"^"first_name"^"last_name"^"email"^"gender"
"1"^"John"^"143 \\"^"
[email protected]"^"Male"
"2"^"Willaim"^"Khan"^"[email protected]"^"Male"{code}
and when i run a drill query (SELECT *
FROM dfs.`C:\Users\achyu\Documents\dir2`)-
I am getting the following error-
{code:java}
UserRemoteException : DATA_READ ERROR: Unexpected character '101' following
quoted value of CSV field. Expecting '94'. Cannot parse CSV input." {code}
This is my dfs configuration for csv in apache drill.I am using the version
1.21.1-
{quote}"csv": \{ "type": "text", "extensions": [ "csv" ], "lineDelimiter":
"\n", "fieldDelimiter": "^", "quote": "\"", "escape": "\\", "comment": "#",
"extractHeader": true }{quote}
Turns out this is because of this particular portion- "143 \\"
In this csv \\ is part of the data and its not an escape character,But as this
character is before the quote its failing. If i just give a space between \\
and quote then it works completely fine.
I guess this is a bug.
Any insights(for escaping the escape character before the quote) or workaround
on the same?
