Class HiveValueWriter

java.lang.Object

org.elasticsearch.hadoop.serialization.builder.FilteringValueWriter<HiveType>

org.elasticsearch.hadoop.hive.HiveValueWriter

All Implemented Interfaces:

org.elasticsearch.hadoop.serialization.builder.ValueWriter<HiveType>, org.elasticsearch.hadoop.serialization.SettingsAware

public class HiveValueWriter
extends org.elasticsearch.hadoop.serialization.builder.FilteringValueWriter<HiveType>

Main value writer for hive. However since Hive expects a Writable type to be passed to the record reader, the raw JSON data needs to be wrapped (and unwrapped by HiveBytesArrayWritable).
