> 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.
