If a column is defined as: col VARCHAR/CHAR NULL and no default value. Then we load json data which misses column col, the result queried is not correct:
+------+
| col |
+------+
| 1 |
+------+
But expect:
+------+
| col |
+------+
| NULL |
+------+

Doris trash include FE catalog recycle bin and BE tablet trash. Users sometimes may be confused abount them. Put them together to let them better understand.
be_custom.conf persistence path is ${doris_home}/conf/be_custom.conf, but if we set ${custom_config_dir} is a different path, will cause be can't read be_custom.conf from ${custom_config_dir}.
set be_custom.conf persist path to ${custom_config_dir}.
Problem:
When window function in aggregation function, executor would report an error like: Required field 'node_type' was not present!
Example:
SELECT SUM(MAX(c1) OVER (PARTITION BY c2, c3)) FROM test_window_in_agg;
Reason:
When analyze aggregate, analytic expr (window function carrior when analyze) transfered to slot and loss message. So when
serialize to thrift package, TExpr can not determine node_type of analytic expr.
Solved:
We do not support aggregate(window function) yet. So we report an error when analyze.
FunctionStringConcat::execute_impl resized with size that include string null terminator, which causes ColumnString::chars.size() does not match with ColumnString::offsets.back, this will cause problems for some string functions, e.g. like and regexp.
* Revert "[fix](executor) only mysql connect to set GlobalPipelineTask (#22205)"
* Revert "[feature](executor) using fe version to set instance_num (#22047)"
return empty result instead of error for empty match query as follows:
`SELECT * FROM t WHERE msg MATCH ''`
`SELECT * FROM t WHERE msg MATCH 'stop_word'`
1. Remove bunch of SQLs related to partition's information
2. Fix the duplicate SQLs submission
3. Fix bug that table's stats not get updated after system job finished
Hive file path may contain temporary directory like this:
drwxrwxrwx - root supergroup 0 2023-03-22 21:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-03-22_21-03-12_047_8461238469577574033-1
drwxrwxrwx - root supergroup 0 2023-05-18 15:03 /usr/hive/warehouse/datalake_performance.db/clickbench_parquet_hits/.hive-staging_hive_2023-05-18_15-03-52_780_3065787006787646235-1
This will cause error when be try to read these files. Need to filter them during FE plan.
