--------------------------------------
Summary: Support Jackson Parser Feature
'ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER' in JSON Reader
Key: DRILL-7060
URL: https://issues.apache.org/jira/browse/DRILL-7060
Project: Apache Drill
Issue Type: Improvement
Components: Storage - JSON
Affects Versions: 1.15.0, 1.16.0
Reporter: Abhishek Girish
Assignee: Abhishek Girish
Fix For: 1.16.0
Some JSON files may have strings with backslashes - which are read as escape
characters. By default only standard escape characters are allowed. So querying
such files would fail. For example see:
Data
{code}
{"file":"C:\Sfiles\escape.json"}
{code}
Error
{code}
(com.fasterxml.jackson.core.JsonParseException) Unrecognized character escape
'S' (code 83)
