Parsing JSON Records on the Spark Engine

Parsing JSON Records on the Spark Engine

In the mapping run-time properties, you can configure how the Spark engine parses corrupt records and multiline records when it reads from JSON sources in a mapping.
Configure the following Hadoop run-time properties:
infaspark.json.parser.mode
Specifies the parser how to handle corrupt JSON records. You can set the value to one of the following modes:
  • DROPMALFORMED. The parser ignores all corrupted records. Default mode.
  • PERMISSIVE. The parser accepts non-standard fields as nulls in corrupted records.
  • FAILFAST. The parser throws an exception when it encounters a corrupted record and the Spark application goes down.
infaspark.json.parser.multiLine
Specifies whether the parser can read a multiline record in a JSON file. You can set the value to true or false. Default is false.
Applies only to Hadoop distributions that use Spark version 2.2.x.
