Dongjoon Hyun commented on SPARK-23443:
---------------------------------------
Hi, [[email protected]].
I have the same need for `ExternalCatalog`, and also tried to provide
`ExternalCatalog` at SPARK-17767
([PR|https://github.com/apache/spark/pull/15336/files]). As you see,
SPARK-17767 was closed as `Later` and included in `Catalog Federation`. I hope
both of us can find a way to achieve that in Apache Spark 2.4.
BTW, I removed the target version here because only Spark committers do that.
> Spark with Glue as external catalog
> -----------------------------------
>
> Key: SPARK-23443
> URL: https://issues.apache.org/jira/browse/SPARK-23443
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Ameen Tayyebi
> Priority: Major
>
> AWS Glue Catalog is an external Hive metastore backed by a web service. It
> allows permanent storage of catalog data for BigData use cases.
> To find out more information about AWS Glue, please consult:
> * AWS Glue - [https://aws.amazon.com/glue/]
> * Using Glue as a Metastore catalog for Spark -
> [https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-spark-glue.html]
> Today, the integration of Glue and Spark is through the Hive layer. Glue
> implements the IMetaStore interface of Hive and for installations of Spark
> that contain Hive, Glue can be used as the metastore.
> The feature set that Glue supports does not align 1-1 with the set of
> features that the latest version of Spark supports. For example, Glue
> interface supports more advanced partition pruning that the latest version of
> Hive embedded in Spark.
> To enable a more natural integration with Spark and to allow leveraging
> latest features of Glue, without being coupled to Hive, a direct integration
> through Spark's own Catalog API is proposed. This Jira tracks this work.
