Matt Lavin created MAPREDUCE-4791:
-------------------------------------
Summary: Javadoc for KeyValueTextInputFormat should include
default separator and how to change it
Key: MAPREDUCE-4791
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4791
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: documentation
Affects Versions: 1.1.0
Reporter: Matt Lavin
Priority: Minor
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"
