Joe Mudd updated MAPREDUCE-5917:
--------------------------------
Attachment: MAPREDUCE-5917.patch
Trunk patch that passes dev-support/test-patch and is ready for code review.
The patch adds two methods to the JobConf() class:
getCount() and getKey(size_t index).
This avoids having to expose an implementation specific map<string,
string>::const_iterator.
> Be able to retrieve configuration keys by index

> Key: MAPREDUCE-5917
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5917
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: pipes
> Affects Versions: trunk
> Reporter: Joe Mudd
> Priority: Minor
> Attachments: MAPREDUCE-5917.patch

>
> The pipes C++ side does not have a configuration key/value pair iterator. It
> is useful to be able to iterate through all of the configuration keys without
> having to expose a C++ map iterator since that is specific to the JobConf
> internals.
