Amazon EMR 6.9.0 - Hive known issues

  • With Amazon EMR 6.6.0 through 6.9.x, INSERT queries with dynamic partition and an ORDER BY or SORT BY clause will always have two reducers. This issue is caused by OSS change HIVE-20703, which puts dynamic sort partition optimization under cost-based decision. If your workload doesn't require sorting of dynamic partitions, we recommend that you set the hive.optimize.sort.dynamic.partition.threshold property to -1 to disable the new feature and get the correctly calculated number of reducers. This issue is fixed in OSS Hive as part of HIVE-22269 and is fixed in Amazon EMR 6.10.0.
