Maxim Gekk updated SPARK-34055:
-------------------------------
Description:
Here is the example to reproduce the issue:
{code:sql}
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
...
{code}
Add new partition by copying the existing one:
{code}
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
{code}
Add new partition and select the table:
{code}
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
{code}
We see only old data.

Here is the example to reproduce the issue:
{code:sql}
spark-sql> create table tbl (col int, part int) using parquet partitioned by
(part);
spark-sql> insert into tbl partition (part=0) select 0;
spark-sql> cache table tbl;
spark-sql> select * from tbl;
0 0
spark-sql> show table extended like 'tbl' partition(part=0);
default tbl false Partition Values: [part=0]
Location:
file:/Users/maximgekk/proj/recover-partitions-refresh-cache/spark-warehouse/tbl/part=0
...
{code}
Add new partition by copying the existing one:
{code}
cp -r
/Users/maximgekk/proj/recover-partitions-refresh-cache/spark-warehouse/tbl/part=0
/Users/maximgekk/proj/recover-partitions-refresh-cache/spark-warehouse/tbl/part=1
{code}
Recover and select the table:
{code}
spark-sql> alter table tbl recover partitions;
spark-sql> select * from tbl;
0 0
{code}
We see only old data.
