MaxGekk opened a new pull request #31379: URL: https://github.com/apache/spark/pull/31379
### What changes were proposed in this pull request? Invoke `CatalogImpl.refreshTable()` in v1 implementation of the `ALTER TABLE .. SET LOCATION` command to refresh cached table data. ### Why are the changes needed? The example below portraits the issue: - Create a source table: ```sql spark-sql> CREATE TABLE src_tbl (c0 int, part int) USING hive PARTITIONED BY (part); spark-sql> INSERT INTO src_tbl PARTITION (part=0) SELECT 0; spark-sql> SHOW TABLE EXTENDED LIKE 'src_tbl' PARTITION (part=0); default src_tbl false Partition Values: [part=0] Location: file:/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0 ... ``` - Set new location for the empty partition (part=0): ```sql spark-sql> CREATE TABLE dst_tbl (c0 int, part int) USING hive PARTITIONED BY (part); spark-sql> ALTER TABLE dst_tbl ADD PARTITION (part=0); spark-sql> INSERT INTO dst_tbl PARTITION (part=1) SELECT 1; spark-sql> CACHE TABLE dst_tbl; spark-sql> SELECT * FROM dst_tbl; 1 1 spark-sql> ALTER TABLE dst_tbl PARTITION (part=0) SET LOCATION '/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0'; spark-sql> SELECT * FROM dst_tbl; 1 1 ``` The last query does not return new loaded data. ### Does this PR introduce _any_ user-facing change? Yes. After the changes, the example above works correctly: ```sql spark-sql> ALTER TABLE dst_tbl PARTITION (part=0) SET LOCATION '/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0'; spark-sql> SELECT * FROM dst_tbl; 0 0 1 1 ``` ### How was this patch tested? Added new test to `org.apache.spark.sql.hive.CachedTableSuite`: ``` $ build/sbt -Phive -Phive-thriftserver "test:testOnly *CachedTableSuite" ``` Authored-by: Max Gekk <max.g...@gmail.com> Signed-off-by: HyukjinKwon <gurwls...@apache.org> (cherry picked from commit d242166b8fd741fdd46d9048f847b2fd6e1d07b1) Signed-off-by: Max Gekk <max.g...@gmail.com> ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
