Apache Spark reassigned SPARK-33478:
------------------------------------
Assignee: Apache Spark
> Allow overwrite a path that is also being read under dynamic partition
> overwrite
> --------------------------------------------------------------------------------
>
> Key: SPARK-33478
> URL: https://issues.apache.org/jira/browse/SPARK-33478
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0, 3.0.1
> Reporter: jinhai
> Assignee: Apache Spark
> Priority: Major
>
> Currently, Insert overwrite cannot overwrite a path that is also being read
> under dynamic partition overwrite.
> In the class DataSourceAnalysis, DDLUtils.verifyNotReadPath is called to
> determine whether it can be overwrite, but in the
> InsertIntoHadoopFsRelationCommand.dynamicPartitionOverwrite method, we need
> to consider the scenario where staticPartitions.size equals
> partitionColumns.length, which should also be allowed to overwrite path this
> is also being read.
> Consider the following statement:
> CREATE TABLE insertTable(i int, part1 int, part2 int) USING PARQUET
> PARTITIONED BY (part1, part2);
> INSERT OVERWRITE TABLE insertTable PARTITION(part1=1, part2=1) SELECT i + 1
> FROM insertTable;
