Which java class handles the output record encoding into files which result from Hive queries

Question

Can anyone suggest which class handles the output record encoding into files which results from Hive queries?

Comments

Why do you want access to "output record encoding generated from Hive queries"?? Anything important that we should be aware of??

Hi,

This is because of Hive uses non-printing characters that are 'delimiters' by default, So when TEXTFILES is used, where it implies all the fields are encoded using alphanumeric characters, and each line is considered a separate record. 

So the record encoding is handled by an input format object and for completeness, there is an output format that Hive uses for writing the output of Queries to files. So for TEXTFILE, the Java class named:

org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat

The above-mentioned class is used for output.
