Answer / Dhirendra Singh

To write your own custom SerDe (Serialized Deserializer) in Apache Hive, follow these steps:
1. Create a Java class that implements the org.apache.hadoop.hive.serde2.SerDe interface.
2. Override the necessary methods like getObjectInspector(), open(), read(org.agoplatform.dal4j.io.serializer.InputStreamImpl, org.agoplatform.dal4j.util.StreamRecord), and close().
3. Compile and package your Java class into a JAR file.
4. Register the custom SerDe with Hive by running the following command:ntALTER TABLE table_name SET SERDEPROPERTIES ("serializer.class"=".your.package.YourCustomSerDe", "deserializer.class"=".your.package.YourCustomSerDe");
