From now, we don't support type derivation for array function's arguments.
So that the cases below will return wrong values or even cause be core.
mysql> select array_union([1],[10000000]);
+----------------------------------------+
| array_union(ARRAY(1), ARRAY(10000000)) |
+----------------------------------------+
| [1, -128] |
+----------------------------------------+
1 row in set (0.03 sec)
mysql> select array_union([NULL],[1]);
ERROR 1105 (HY000): RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason
mysql> select array_union([],[1]);
ERROR 1105 (HY000): RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason
This commit make a small fix to derivate the argument types of the array function
1、 For null type in arguments, cast the null type to boolean type, because null type should not be seen in be.
2、For different types in arguments, cast all arguments type to their compatible type.
Users do not need to set create_table_timeout, it is a ddl command and when encounter a timeout event
users will set a lager timeout and retry.
Stream load 2pc is used by default in flink connector, so we should not disable it by config, the config
item is useless.
* [fix](streamload) report exactly error message when be does not receive heartbeat from fe
Http service is started before hearbeat from fe, so if a streamload comes before heartbeat
from fe, then be report an error like below because master address is not set.
"Couldn't open transport for :0 (Could not resolve host for client socket.)".
How to reproduce:
1. create a table with replica allocation, eg:
```
"replication_allocation"="tag.location.group_01:1, tag.location.group_02:1, tag.location.group_03:1"
```
2. Backup this table
3. Restore this table with specific replication allocation, eg: `"replication_allocation" = "tag.location.default: 3"`
4. After restore, executing `show create table xxx`, you will be the `replication_allocation` is still:
```
"replication_allocation"="tag.location.group_01:1, tag.location.group_02:1, tag.location.group_03:1"
```
Not what we expected
5. But if you execute `show partitions from xxx`, the replication allocation of each partition is what we expected:
```
"replication_allocation" = "tag.location.default: 3"
```
This is because when doing restore job, we forget to set the "default" replica allocation property of the table.
And the result of `show create table` is got from "default" replica allocation property, not from the real replica property of each partition
There are some errors occur when building FE by JDK (arm64) on M1 because the dependencies protoc and grpc-java doesn't support M1.
#13563 modified the build.sh to fix this issues by adding -Dos.arch=x86_64 to build command.
However, if some one executes `mvn clean package -DskipTests=true` under the folder fe, the errors will occur again.
This PR introduces a better way to fix them.
1. Missing field and line delimiter
2. When query external table with text(csv) format, we should pass the column position map to BE,
otherwise the column order is wrong.
TODO:
1. For now, if we query csv file with non-exist column, it will return null.
But it should return null or default value of that column.
2. Add regression test after hive docker is ready.
The regression test may failed because of heartbeat failure occasionally.
So I add 2 new FE config to relax this limit
1. `disable_backend_black_list`
Set to true to not put Backend to black list even if we failed to send task to it. Default is false.
2. `max_backend_heartbeat_failure_tolerance_count`
Only if the failure time of heartbeat exceed this config, we can set Backend as dead. Default is 1.
this pr is used to fix the wrong result of array_join function.
before the change, the array_join function will return wrong result.
MySQL [example_db]> select array_join(["", "1", "2"], '');
+--------------------------------------+
| array_join(ARRAY('', '1', '2'), '') |
+--------------------------------------+
| 1_2 |
+--------------------------------------+
3.after the change, the array_join function will return correct result.
MySQL [example_db]> select array_join(["", "1", "2"], '');
+--------------------------------------+
| array_join(ARRAY('', '1', '2'), '') |
+--------------------------------------+
| _1_2 |
+--------------------------------------+
Issue Number: #7570
1. Modify default behavior of `build.sh`
The `BUILD_JAVA_UDF` is default ON, so that jvm is needed for compilation and runtime.
2. Add docker-compose for MySQL 5.7, PostgreSQL 14 and Hive 2
See `docker/thirdparties/docker-compose`.
3. Add some regression test cases for jdbc query on MySQL, PG and Hive Catalog
The default is `false`, if set to true, you need first start docker for MySQL/PG/Hive.
4. Support `if not exists` and `if exists` for create/drop resource and create/drop encryptkey
Fix for SQL with array column:
delete from tbl where c_array is null;
more info please refer to #13360

We should consider memory which are being flushed from memtable to disk when trying to reduce memory by flushing memtable. Otherwise, we might not release memory space as expected. (e.g. lots of large memtable is in flush, the reduce_mem_usage method picks some small memtables to flush, it can't release enough memory and also can generate lots of small segments, which can cause -238 error)
Overwrite the environment variable PATH to avoid using binutils from Homebrew to build third parties which may cause compilation errors.
