Question 57/72
Your customer receives data in JSON format.
Which option should you use to load this data into Hive tables?
Which option should you use to load this data into Hive tables?
Correct Answer: E
Explanation/Reference:
SerDe is short for Serializer/Deserializer. Hive uses the SerDe interface for IO. The interface handles both serialization and deserialization and also interpreting the results of serialization as individual fields for processing.
A SerDe allows Hive to read in data from a table, and write it back out to HDFS in any custom format.
Anyone can write their own SerDe for their own data formats.
The JsonSerDe for JSON files is available in Hive 0.12 and later.
