In the above code, LONG_VALUE_SUM is a string denoting the aggregation type LongValueSum, which sums over long values.
-ONE denotes a string "1". Function generateEntry(LONG_VALUE_SUM, words[i], ONE) will inperpret the first argument as an aggregation type, the second as an aggregation ID, and the the third argumnent as the value to be aggregated. The output will look like: "LongValueSum:xxxx", where XXXX is the string value of words[i]. The value will be "1". The mapper will call generateKeyValPairs(Object key, Object val) for each input key/value pair to generate the desired aggregation id/value pairs.

When an executable is specified for mappers, each mapper task will launch the executable as a separate process when the mapper is initialized. As the mapper task runs, it converts its inputs into lines and feed the lines to the stdin of the process. In the meantime, the mapper collects the line oriented outputs from the stdout of the process and converts each line into a key/value pair, which is collected as the output of the mapper. By default, the
- <em>prefix of a line up to the first tab character</em> is the <strong>key</strong> and the the rest of the line (excluding the tab character) will be the <strong>value</strong>.
+ <em>prefix of a line up to the first tab character</em> is the <strong>key</strong> and the rest of the line (excluding the tab character) will be the <strong>value</strong>.
If there is no tab character in the line, then entire line is considered as key and the value is null. However, this can be customized, as discussed later.

However, you can customize this default. You can specify a field separator other than the tab character (the default), and you can specify the nth (n >= 1) character rather than the first character in a line (the default) as the separator between the key and value. For example:

However, you can customize this default. You can specify a field separator other than the tab character (the default), and you can specify the nth (n >= 1) character rather than the first character in a line (the default) as the separator between the key and value. For example:
