Subject [jira] [Created] (MAPREDUCE-4791) Javadoc for KeyValueTextInputFormat should include default separator and how to change it
Date Tue, 13 Nov 2012 02:07:12 GMT
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"
