mapred.reduce.tasks
- Default Value: -1
...
- Added In: ?
The default number of reduce tasks per job. Typically set to a prime close to the number of available hosts. Ignored when mapred.job.tracker is "local". Hadoop set this to 1 by default, whereas hive uses -1 as its default value. By setting this property to -1, Hive will automatically figure out what should be the number of reducers.
hive.region.properties
- Default Value: (empty)
- Added In: ?
The default filesystem and jobtracker for a region.
