> Very slow query when using Oracle hive metastore and table has lots of
> partitions
> ----------------------------------------------------------------------------------
>
> Key: SPARK-5923
> URL: https://issues.apache.org/jira/browse/SPARK-5923
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.2.0
> Reporter: Matthew Taylor
>
> This has two aspects
> * The direct sql support for oracle is broken in hive 0.13.1. Fails when
> partitions get bigger than 1000 due oracle limitation on IN clause. This
> cause fall back to ORM which is very slow(20 minutes to even start the query)
> * Hive it self does not suffer this problem as it passes down to the metadata
> query, filter terms that restrict the partitions returned. SparkSQL is always
> asking for all partitions event if they are not all needed. Even when we
> patched hive it was still taking 2 minutes
