Maxim Gekk updated SPARK-34027:
-------------------------------
Description:
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
Serde Library: org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe
InputFormat: org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat
OutputFormat: org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat
Storage Properties: [serialization.format=1,
path=file:/Users/maximgekk/proj/recover-partitions-refresh-cache/spark-warehouse/tbl]
Partition Parameters: {transient_lastDdlTime=1609929762, totalSize=424,
numFiles=1}
Created Time: Wed Jan 06 13:42:42 MSK 2021
Last Access: UNKNOWN
Partition Statistics: 424 bytes
{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.

Here is the example to reproduce the issue:
{code:sql}
spark-sql> CREATE TABLE tbl1 (col0 int, part0 int) USING parquet PARTITIONED BY
(part0);
spark-sql> INSERT INTO tbl1 PARTITION (part0=0) SELECT 0;
spark-sql> INSERT INTO tbl1 PARTITION (part0=1) SELECT 1;
spark-sql> CACHE TABLE tbl1;
spark-sql> SELECT * FROM tbl1;
0 0
1 1
spark-sql> ALTER TABLE tbl1 PARTITION (part0 = 0) RENAME TO PARTITION (part0 =
2);
spark-sql> SELECT * FROM tbl1;
0 0
1 1
{code}
