> Here's one that [~cdrome] and [~thiruvel] worked on:
> We found that certain Hadoop Map/Reduce settings that are set in site config files do not take effect in Hive jobs, because the Tez site configs do not contain the same settings.
> In Yahoo's case, the problem was that, at the time, there was no mapping between {{MRJobConfig.COMPLETED_MAPS_FOR_REDUCE_SLOWSTART}} and {{TEZ_SHUFFLE_VERTEX_MANAGER_MAX_SRC_FRACTION}}. There were situations where significant capacity on production clusters were being used up doing nothing, while waiting for slow tasks to complete. This would have been avoided, were the mappings in place.
> Tez provides a {{DeprecatedKeys}} utility class, to help map MR settings to Tez settings. Hive should use this to ensure that the mappings are in sync.
