List Partitioning
-----------------
Key: HIVE-1602
URL: https://issues.apache.org/jira/browse/HIVE-1602
Project: Hadoop Hive
Issue Type: New Feature
Affects Versions: 0.7.0
Reporter: Ning Zhang
Dynamic partition inserts create partitions bases on the dynamic partition
column values. Currently it creates one partition for each distinct DP column
value. This could result in skews in the created dynamic partitions in that
some partitions are large but there could be large number of small partitions
as well. This results in burdens in HDFS as well as metastore. A list
partitioning scheme that aggregate a number of small partitions into one big
one is more preferable for skewed partitions.
