Aaron Kimball commented on MAPREDUCE-750: ----------------------------------------- I should point out -- I'm all for not cluttering up the mapred-, hdfs- and core-* config files with extraneous parameters. Is there a better place to put this? Can/should we have a contrib-default and contrib-site? (Or, inevitably, per-contrib-module config files?) > Extensible ConnManager factory API > ---------------------------------- > > Key: MAPREDUCE-750 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-750 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: contrib/sqoop > Reporter: Aaron Kimball > Assignee: Aaron Kimball > Attachments: MAPREDUCE-750.patch > > > Sqoop uses the ConnFactory class to instantiate a ConnManager implementation > based on the connect string and other arguments supplied by the user. This > allows per-database logic to be encapsulated in different ConnManager > instances, and dynamically chosen based on which database the user is > actually importing from. But adding new ConnManager implementations requires > modifying the source of a common ConnFactory class. An indirection layer > should be used to delegate instantiation to a number of factory > implementations which can be specified in the static configuration or at > runtime. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
