Hive parses JSON string

Hive generally has two directions for processing json data:

1. Enter the entire json into the Hive table as a string, and then use the UDF function to parse the data that has been imported into hive, such as using the LATERAL VIEW json_tuplemethod to obtain the required column names.

2. Split json into various fields before importing, and the data imported into the Hive table has already been parsed. This will require the use of a third party SerDe.
