Subject [jira] Commented: (MAPREDUCE-2151) [rumen] Add a map of jobconf key-value pairs in LoggedJob
Date Fri, 29 Oct 2010 00:27:24 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926021#action_12926021

Hong Tang commented on MAPREDUCE-2151:

What are included in the patch I uploaded:
- Added a Map<String, String> field named "configuration" in LoggedJob.
- Changed JobConfigurationParser to handle extraction based on prefix. Also handle a special
case to extract all key-value pairs (by specifying the interested prefix list to be null).
- Added a StringTrie that supports the partial matching needed for JobConfigurationParser.
- Added unit tests for JobConfigurationParser and StringTrie.
- Updated the existing unit tests (the golden files to include the configuration object).
