Summary: JSON SerDe Re-Write
Key: HIVE-21240
URL: https://issues.apache.org/jira/browse/HIVE-21240
Project: Hive
Issue Type: Improvement
Components: Serializers/Deserializers
Affects Versions: 3.1.1, 4.0.0
Reporter: BELUGA BEHR
Fix For: 4.0.0
The JSON SerDe has a few issues, I will link them to this JIRA.
* Use Jackson Tree parser instead of manually parsing
* Added support for base-64 encoded data (the expected format when using JSON)
* Added support to skip blank lines (returns all columns as null values)
* Current JSON parser accepts, but does not apply, custom timestamp formats in
most cases
* Added some unit tests
* Added cache for column-name to column-index searches, currently O\(n\) for
each row processed, for each column in the row
