Mapreduce– textinputformat.record.delimiter

The default input format of hadoop mapreduce is text input format. This means it reads text files.

The default delimiter is ‘/n’. This means, it reads line by line.
But reading line by line may not be favourable for us in all the cases. So we can make it read based on our on delimiter rather than the default delimiter ‘/n’.

This can be done by setting a property textinputformat.record.delimiter .

This property can be set either in the program or while running the program in the cli.

The format for setting it in the program (Driver class)  is  conf.set(“textinputformat.record.delimiter”, “delimiter”) .
