Main subtask of [DSIP-28](https://cwiki.apache.org/confluence/display/DORIS/DSIP-028%3A+Suppot+MySQL+Load+Data)
## Problem summary
Support mysql load syntax as below:
```sql
LOAD DATA
[LOCAL]
INFILE 'file_name'
INTO TABLE tbl_name
[PARTITION (partition_name [, partition_name] ...)]
[COLUMNS TERMINATED BY 'string']
[LINES TERMINATED BY 'string']
[IGNORE number {LINES | ROWS}]
[(col_name_or_user_var [, col_name_or_user_var] ...)]
[SET (col_name={expr | DEFAULT} [, col_name={expr | DEFAULT}] ...)]
[PROPERTIES (key1 = value1 [, key2=value2]) ]
```
For example,
```sql
LOAD DATA
LOCAL
INFILE 'local_test.file'
INTO TABLE db1.table1
PARTITION (partition_a, partition_b, partition_c, partition_d)
COLUMNS TERMINATED BY '\t'
(k1, k2, v2, v10, v11)
set (c1=k1,c2=k2,c3=v10,c4=v11)
PROPERTIES ("auth" = "root:", "strict_mode"="true")
```
Note that in this pr the property named `auth` must be set since stream load need auth. I will optimize it later.
The internal statistic table column_statistics has a non-null field idx_id, the insert sql for hive table set the default value to NULL, which will failed to insert the result. Change it to -1.
External hms catalog table column names in doris are all in lower case,
while iceberg table or spark-sql created hive table may contain upper case column name,
which will cause empty query result. This pr is to fix this bug.
1. For parquet file, transfer all column names to lower case while parse parquet metadata.
2. For orc file, store the origin column names and lower case column names in two vectors, use the suitable names in different cases.
3. FE side, change the column name back to the origin column name in iceberg while doing convertToIcebergExpr.
When execute show load profile '/', the value of SQL and DefaultDb columns are all 'N/A', but we can fill these fields，the result of this pr is as follows:
Execute show load profile '/'\G:
MySQL [test_d]> show load profile '/'\G

This pr fix two bugs:
_jdbc_scanner may be nullptr in vjdbc_connector.cpp, so we use another method to count jdbc statistic. close [Enhencement](jdbc scanner) add profile for jdbc scanner #15914
In the batch insertion scenario, oracle database does not support syntax insert into tables values (...),(...); , what it supports is:
insert all
into table(col1,col2) values(c1v1, c2v1)
into table(col1,col2) values(c1v2, c2v2)
SELECT 1 FROM DUAL;
GRANT USAGE_PRIV ON RESOURCE * TO user;
user will see all database
Describe your changes.
Set a PrivPredicate for show resources and remove USAGE under PrivPredicate in SHOW_ PRIV
This PR #14381 limit the `ExtractCommonFactorsRule` to handle only `WHERE` predicate,
but the predicate in `ON` clause should also be considered. Such as:
```
CREATE TABLE `nation` (
`n_nationkey` int(11) NOT NULL,
`n_name` varchar(25) NOT NULL,
`n_regionkey` int(11) NOT NULL,
`n_comment` varchar(152) NULL
)
DUPLICATE KEY(`n_nationkey`)
DISTRIBUTED BY HASH(`n_nationkey`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 1"
);
select * from
nation n1 join nation n2
on (n1.n_name = 'FRANCE' and n2.n_name = 'GERMANY')
or (n1.n_name = 'GERMANY' and n2.n_name = 'FRANCE')
```
There should be predicates:
```
PREDICATES: `n1`.`n_name` IN ('FRANCE', 'GERMANY')
PREDICATES: `n2`.`n_name` IN ('FRANCE', 'GERMANY')
```
On each scan node.
This PR fix this issue by removing the limit of `ExtractCommonFactorsRule`
1. Spark dpp
Move `DppResult` and `EtlJobConfig` to sparkdpp package in `fe-common` module.
So taht `fe-core` is longer depends on `spark-dpp` module, so that the `spark-dpp.jar`
will not be moved into `fe/lib`, which reduce the size of FE output.
2. Modify start_fe.sh
Modify the CLASSPATH to make sure that doris-fe.jar is at front, so that
when loading classes with same qualified name, it will be got from doris-fe.jar firstly.
3. Upgrade hadoop and hive version
hadoop: 2.10.2 -> 3.3.3
hive: 2.3.7 -> 3.1.3
4. Override the IHiveMetastoreClient implementations from dependency
`ProxyMetaStoreClient.java` for Aliyun DLF.
`HiveMetaStoreClient.java` for origin Apache Hive metastore.
Because I need to modified some of their method to make them compatible with
different version of Hive.
5. Exclude some unused dependencies to reduce the size of FE output
Now it is only 370MB (Before is 600MB)
6. Upgrade aws-java-sdk version to 1.12.31
7. Support AWS Glue Data Catalog
8. Remove HudiScanNode(no longer support)
1. add TypeCoercion for (string, decimal) and (date, decimal)
2. The equality of LogicalProject node should consider children in some case
3. don't push down join condition like "t1 join t2 on true/false"
4. add PUSH_DOWN_FILTERS after FindHashConditionForJoin
5. nestloop join should support all kind of join
6. the intermediate tuple should contains slots from both children of nest loop join.
1. support row format using codec of jsonb
2. short path optimize for point query
3. support prepared statement for point query
4. support mysql binary format
Support iceberg schema evolution for parquet file format.
Iceberg use unique id for each column to support schema evolution.
To support this feature in Doris, FE side need to get the current column id for each column and send the ids to be side.
Be read column id from parquet key_value_metadata, set the changed column name in Block to match the name in parquet file before reading data. And set the name back after reading data.
