what is record container class in sqoop

The record container class in Sqoop is a generated Java class that can reinterpret the text files generated by Sqoop when importing data to HDFS. It can also serialize and deserialize data to and from the SequenceFile format, and parse the delimited-text form of a record. The generated record container class communicates with both the Sqoop client and MapReduce job. It is used for determining the nature of the serialization of the data present in the source database.
