liurenjie1024 opened a new issue, #13873:
URL: https://github.com/apache/iceberg/issues/13873
### Apache Iceberg version
1.6.1
### Query engine
Spark
### Please describe the bug 🐞
1. Run `mkdir warehouse/default` to create dir
2. Download attachment for table data
3. Run `tar -xzf iceberg.tar.gz -C warehouse/default` to put table data into
dir
4. Start spark shell
```
/home/ubuntu/Apps/spark-3.5.4-bin-hadoop3/bin/spark-sql \
--packages org.apache.iceberg:iceberg-spark-runtime-3.5_2.12:1.9.2\
--conf
spark.sql.catalog.spark_catalog=org.apache.iceberg.spark.SparkCatalog \
--conf spark.sql.catalog.spark_catalog.type=hadoop \
--conf spark.sql.catalog.spark_catalog.warehouse=Workspace/warehouse
```
5. Run count(*) it shows 705 rows.
```
spark-sql (default)> select count(*) from tmp_table_gw0_374721098_0;
705
Time taken: 2.726 seconds, Fetched 1 row(s)
```
6. Run ```select * from tmp_table_gw0_374721098_0``` it reports fetching
rows not 750 rows.
```
spark-sql (default)> select * from tmp_table_gw0_374721098_0;
...
Time taken: 0.403 seconds, Fetched 723 row(s)
```
The oddest part is that the difference only happens when *the first time*
you run `select *` after `select count(*)`, after that when you run `select *`
everything is back to normal.
I tested againts 1.6.1, 1.7.2, and 1.9.2, buth all failed.
