Edward Capriolo updated HIVE-4825: ---------------------------------- Priority: Minor (was: Major) Issue Type: Improvement (was: Bug) > Separate MapredWork into MapWork and ReduceWork > ----------------------------------------------- > > Key: HIVE-4825 > URL: https://issues.apache.org/jira/browse/HIVE-4825 > Project: Hive > Issue Type: Improvement > Reporter: Gunther Hagleitner > Assignee: Gunther Hagleitner > Priority: Minor > Attachments: HIVE-4825.1.patch, HIVE-4825.2.code.patch, > HIVE-4825.2.testfiles.patch > > > Right now all the information needed to run an MR job is captured in > MapredWork. This class has aliases, tagging info, table descriptors etc. > For Tez and MRR it will be useful to break this into map and reduce specific > pieces. The separation is natural and I think has value in itself, it makes > the code easier to understand. However, it will also allow us to reuse these > abstractions in Tez where you'll have a graph of these instead of just 1M and > 0-1R. -- This message is automatically generated by JIRA.
