LakshSingla opened a new pull request #12259:
URL: https://github.com/apache/druid/pull/12259
### Description
This PR aims to make the `ParseExceptions` in Druid more informative, by
adding the input line number where the exception occurred, and the source which
generated the exception. A `ParseException.Builder` is also added to make the
creation of the `ParseException`s easier.
This will also help in triaging the issues when `InputSourceReader`
generates `ParseException`s because it can point to the specific `InputEntity`
which caused the exception (while trying to read it).
