There was a problem hiding this comment.
The most risky bug in this code is:
Potential null pointer dereference due to `db` being null.
You can modify the code like this:
public static void checkDbExistInResourceGroupAndReport(String dbName) {
Database db = GlobalStateMgr.getCurrentState().getLocalMetastore().getDb(dbName);
if (db == null) {
ErrorReport.reportSemanticException(ErrorCode.ERR_BAD_DB_ERROR, dbName);
return;
}
GlobalStateMgr.getCurrentState().getResourceGroupMgr().getAllResourceGroupNames().forEach(rgName -> {
GlobalStateMgr.getCurrentState().getResourceGroupMgr().getResourceGroup(rgName).getClassifiers().forEach(classify -> {
if (classify.getDatabases().contains(db.getId())) {
ErrorReport.reportSemanticException(ErrorCode.ERR_DROP_DATABASE, dbName, rgName);
}
});
});
}

Why I'm doing:
If delete a database which was bounded to a resource group, the resource group will become invalid. Therefore, we need to check whether a database was bound to a resource group before deleting it
What I'm doing:
