[jira] [Commented] (SPARK-15348) Hive ACID
[ https://issues.apache.org/jira/browse/SPARK-15348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16893806#comment-16893806 ]
Abhishek Somani commented on SPARK-15348:
-----------------------------------------
We have worked on and open sourced a datasource that will enable users to work on their Hive ACID Transactional tables using Spark.
Github: [https://github.com/qubole/spark-acid]
It is available as a Spark package and instructions to use it are on the Github page. Currently the datasource supports only reading from Hive ACID tables, and we are working on adding the ability to write into these tables via Spark as well.
Feedback and suggestions are welcome!

> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 1.6.3, 2.0.2, 2.1.2, 2.2.0, 2.3.0
> Reporter: Ran Haim
> Priority: Major
>
> Spark does not support any feature of hive's transnational tables,
> you cannot use spark to delete/update a table and it also has problems reading the aggregated data when no compaction was done.
> Also it seems that compaction is not supported - alter table ... partition .... COMPACT 'major'
