Maxim Gekk updated SPARK-34262:
-------------------------------
Description:
The example below portraits the issue:
1. Create a source table:
{code: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
...
{code}
2. Load data from the source table to a cached destination table:
{code: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
{code}
The last query does not show recently loaded data from the source table.
