For eg. you will find Text for String. IntWritable instead of Integer. For all primitive types you will see a type which implements Writable interface.<\/p>\n
Serialization and Deserialization are at the heart of Hadoop implementation. Data is distributed in Hadoop and data is transferred over the network multiple times during shuffle mainly. Data is serialized when the data is transferred over the network and deserialized when data is processed on the other side.<\/span><\/p>\n Plain Java serialization is heavy and slow.<\/span><\/p>\n To overcome the inefficiencies with Java serialization Hadoop\u2019s creator Doug Cutting implemented Writable objects that came up with IO classes to replace Java primitive types which can perform serialization that is fast and compact.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" In Hadoop you will find Hadoop specific types for basic types.
