[jira] [Updated] (MAPREDUCE-5917) Be able to retrieve configuration keys by index

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> 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.
