Mariappan Asokan commented on HIVE-6476: ---------------------------------------- Sushanth, thank you. This is very helpful. I will dig into the code and if I have any questions I will let you know. Is FileOutputCommitterContainer.java a good place to start? Can I assign this Jira to me? > Support Append with Dynamic Partitioning > ---------------------------------------- > > Key: HIVE-6476 > URL: https://issues.apache.org/jira/browse/HIVE-6476 > Project: Hive > Issue Type: Sub-task > Components: HCatalog, Metastore, Query Processor, Thrift API > Reporter: Sushanth Sowmyan > > Currently, we do not support mixing dynamic partitioning and append in the > same job. One reason is that we need exhaustive testing of corner cases for > that, and a second reason is the behaviour of add_partitions. To support > dynamic partitioning with append, we'd have to have a > add_partitions_if_not_exist call, rather than an add_partitions call. > Thus, the current implementation in HIVE-6475 assumes immutability for all > dynamic partitioning jobs, irrespective of whether or not the table is marked > as mutable or not. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
