Description

The javadoc for KeyValueTextInputFormat says "Each line is divided into key and value parts by a separator byte" but it doesn't say what the separator byte is or how to change it.

After some exploration I noticed that the default is the Tab character and that the value can be changed by the JobConf value "key.value.separator.in.input.line"
