      Description

      Here is the example to reproduce the issue:

      spark-sql> create table tbl2 (col int, part int) partitioned by (part);
      spark-sql> insert into tbl2 partition (part=0) select 0;
      spark-sql> cache table tbl2;
      spark-sql> select * from tbl2;
      0	0
      spark-sql> show table extended like 'tbl2' partition (part = 0);
      default	tbl2	false	Partition Values: [part=0]
      Location: file:/Users/maximgekk/proj/add-partition-refresh-cache-2/spark-warehouse/tbl2/part=0
      ...
      

      Add new partition by copying the existing one:

      cp -r /Users/maximgekk/proj/add-partition-refresh-cache-2/spark-warehouse/tbl2/part=0 /Users/maximgekk/proj/add-partition-refresh-cache-2/spark-warehouse/tbl2/part=1
      

       Add new partition and select the table:

      spark-sql> alter table tbl2 add partition (part = 1) location '/Users/maximgekk/proj/add-partition-refresh-cache-2/spark-warehouse/tbl2/part=1';
      spark-sql> select * from tbl2;
      0	0
      

      We see only old data.
