I have referred to the official license requirements at https://dolphinscheduler.apache.org/zh-cn/docs/3.2.2/contribute/join/DS-License. It is necessary to add a description of the newly introduced third-party library in tools/dependencies/known-dependencies.txt, but it seems to conflict with #16838. What should I do now to comply with the requirements? @SbloodyS

[eco8848]

The CI errors have already been fixed. @SbloodyS

I saw that there is a new check requires a milestone label. So is there a general plan for the integration of this PR? @SbloodyS

The condition incorrectly checks for DbType.REDSHIFT instead of DbType.DOLPHINDB, which may lead to incorrect host validation. Adjust the condition to compare against DbType.DOLPHINDB.

Suggested change

	if (!baseDataSourceParamDTO.getType().equals(DbType.REDSHIFT)) {
	// due to redshift use not regular hosts
	if (baseDataSourceParamDTO.getType().equals(DbType.DOLPHINDB)) {
	// validate host for DolphinDB
