> Key: SPARK-33187
> URL: https://issues.apache.org/jira/browse/SPARK-33187
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.1
> Reporter: jinhai
> Priority: Major
>
> In the method Shim#getPartitionsByFilter, when filter is empty or when the hive table has a large number of partitions, calling getAllPartitionsMethod or getPartitionsByFilterMethod will results in Driver OOM.
> I think we need add a check on the number of returned partitions by calling Hive#getNumPartitionsByFilter, and add SQLConf spark.sql.hive.metastorePartitionLimit, default value is 100_000
