bitmap filter is implemented before mark-join. When support mark-join, we forgot to update the bitmap-filter branch.
when convert a bitmap-apply-in to join, we should set markjoinReference to the join if there are markJoinRefereneces

sql like this:
select col1, col2 from (select a as col1, a as col2 from mal_test1 group by a) t group by col1, col2 ;
Transformation Description:
In the process of optimizing the query, an agg-project-agg pattern is transformed into a project-agg pattern:
Before Transformation:
LogicalAggregate
+-- LogicalPrject
+-- LogicalAggregate
After Transformation:
LogicalProject
+-- LogicalAggregate
Before the transformation, the projection in the LogicalProject was a AS col1, a AS col2, and the outer aggregate group by keys were col1, col2. After the transformation, the aggregate group by keys became a, a, and the projection remained a AS col1, a AS col2.
Problem:
When building the project projections, the group by key a, a needed to be transformed to a AS col1, a AS col2. The old code had a bug where it used the slot as the map key and the alias in the projections as the map value. This approach did not account for the situation where aliases might have the same slot.
Solution:
The new code fixes this issue by using the original outer aggregate group by expression's exprId. It searches within the original project projections to find the NamedExpression that has the same exprId. These expressions are then placed into the new projections. This method ensures that the correct aliases are maintained, resolving the bug.
Previously, the limitation on whether operations can be performed on materialized views was to determine `opType`.
Now, a `allowOpMTMV()` method is implemented through various `clauses`.
Because some operations have the same `opType`, but some operations allow and some do not.
For example, the `opType` for both `add column` and `create index` is `SCHEMA-CHANGE`, but `add column` is not allowed and `create index` is allowed.
Problem:
When using multiple be to test hint with distribute hint, the result would be unstable
Solved:
Add ordered hint to every distribute hint and move some leading hint cases to check containing of hint infomation
The following sql and when the dictionary column contains functions related to null, the results will be incorrect.
```
select * from ( select IF(o_orderpriority IS NULL, 'null', o_orderpriority) AS o_orderpriority from test_string_dict_filter_orc ) as A where o_orderpriority = 'null';
```
```
select * from ( select IFNULL(o_orderpriority, 'null') AS o_orderpriority from test_string_dict_filter_parquet ) as A where o_orderpriority = 'null'
```
```
select * from ( select COALESCE(o_orderpriority, 'null') AS o_orderpriority from test_string_dict_filter_parquet ) as A where o_orderpriority = 'null';
```
Hive's test environment uses docker, so when using 127.0.0.1,
BE will write the file to the docker of its own machine.
But if FE and are not on the same machine,
FE cannot read this file because it can only read docker on its own machine.
Therefore, the address 127.0.0.1 cannot be used in the test environment.
1. `memory.usage_in_bytes ~= free.used + free.(buff/cache) - (buff)`, free cache can be reused,
so, modify cgroup_memory_usage = memory.usage_in_bytes - memory.meminfo["Cached"].
2. If system not configured with cgroup, find cgroup file path will failed, refactor refresh cgroup memory info, compatible with find failed.
In this pull request, we optimize the ordering of children in the Intersect operator to improve query performance. The proposed change is to place the child with the least row count in the first position of the Intersect operator.
The rationale behind this optimization is that the Intersect operator works by first evaluating the leftmost child and then iterating through the results of the other children to find matching rows. By placing the child with the least row count first, we can minimize the number of iterations required to find the matching rows, thereby reducing the overall execution time of the query.
