[jira] [Updated] (SPARK-36727) Support sql overwrite a path that is
also being read from when partitionOverwriteMode is dynamic
[ https://issues.apache.org/jira/browse/SPARK-36727?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tongwei updated SPARK-36727:
----------------------------
Description:
{code:java}
// non-partitioned table overwrite
CREATE TABLE tbl (col1 INT, col2 STRING) USING PARQUET;
INSERT OVERWRITE TABLE tbl SELECT 0,1;
INSERT OVERWRITE TABLE tbl SELECT * FROM tbl;
// partitioned table static overwrite
CREATE TABLE tbl (col1 INT, col2 STRING) USING PARQUET PARTITIONED BY (pt1 INT);
INSERT OVERWRITE TABLE tbl PARTITION(p1=2021) SELECT 0 AS col1,1 AS col2;
INSERT OVERWRITE TABLE tbl PARTITION(p1=2021) SELECT col1, col2 FROM WHERE p1=2021;
{code}
When we run the above query, an error will be throwed "Cannot overwrite a path that is also being read from"
