❌ Codacy found a critical Security issue: Hardcoded passwords are a security risk.

The issue identified by the Semgrep linter is that the variable password is being initialized as an empty string, which can be interpreted as a hardcoded password. Hardcoded passwords are a security risk because they can be easily exploited if the source code is accessed by unauthorized individuals. Instead of hardcoding passwords in the code, they should be securely retrieved from a configuration file, environment variable, or a secrets management service.

To address this issue, a single line change could be made to initialize the password variable by retrieving it from an environment variable, which is a more secure approach.

❌ Codacy found a critical Complexity issue: Method Consumergroup::main has 273 lines of code (limit is 100)

The issue reported by the Lizard linter indicates that the main method has too many lines of code (273 lines), which exceeds the recommended limit of 100 lines. This can lead to reduced readability and maintainability of the code. To address this issue, it is advisable to refactor the code by extracting some of the logic into separate methods.

Here’s a single line code suggestion that encapsulates the database connection and SQL execution logic into a new method called executeDatabaseScript:

In this case, you would also need to implement the executeDatabaseScript method to handle the logic currently in the main method, which would significantly reduce the length of the main method while improving code organization.

❌ Codacy found a critical Complexity issue: Method Consumergroup::main has a cyclomatic complexity of 28 (limit is 10)

The issue reported by the Lizard linter indicates that the main method has a cyclomatic complexity of 28, which exceeds the recommended limit of 10. Cyclomatic complexity is a metric used to measure the complexity of a program by counting the number of linearly independent paths through the code. A high cyclomatic complexity suggests that the method may be doing too much or has too many conditional branches, making it harder to understand, maintain, and test.

To reduce the complexity, we can refactor the code by extracting the database connection and SQL execution logic into a separate method. This will help simplify the main method and improve readability.

Here's the suggested single line change to achieve this:

This assumes that you would create a new method called executeDatabaseSetup() that contains the logic currently present in the main method, effectively reducing the cyclomatic complexity of main.

⚠️ Codacy found a medium Complexity issue: Method Consumergroup::createTopic has 8 parameters (limit is 5)

The issue identified by the Lizard linter is that the method createTopic has too many parameters—specifically, it has 8 parameters, exceeding the recommended limit of 5. This can lead to reduced readability and maintainability of the code, as it becomes harder to understand the method's purpose and the role of each parameter.

To address this issue, one common approach is to encapsulate related parameters into a single object. In this case, we could create a TopicConfig class to hold the parameters related to creating a topic.

Here's a single line change to suggest using a new object to encapsulate the parameters:

You would then define the TopicConfig class to include partitions, replicas, retentionms, cleanuppolicy, organization, and description. This change reduces the number of parameters in the createTopic method and improves code clarity.

⚠️ Codacy found a medium Complexity issue: Method Consumergroup::getCredentials has 55 lines of code (limit is 50)

The issue reported by the Lizard linter indicates that the getCredentials method has exceeded the recommended line limit of 50 lines, with a total of 55 lines. This suggests that the method may be doing too much and could benefit from being broken down into smaller, more manageable methods. Reducing the complexity of the method can improve readability and maintainability.

A straightforward way to address this issue is to extract the database query logic into a separate private method. This will help reduce the number of lines in the getCredentials method while keeping the functionality intact.

Here's a code suggestion that encapsulates the database query logic in a new method, thus reducing the line count in getCredentials:

In this suggestion, fetchCredentials would be a new method that you would implement to handle the database connection and query execution, allowing getCredentials to simply call this new method and return its result.

❌ Codacy found a critical ErrorProne issue: Use COPY instead of ADD for files and folders

The issue identified by Hadolint regarding the use of ADD instead of COPY is based on best practices in Dockerfile optimization. The ADD instruction is more powerful than COPY because it can handle remote URLs and automatically extract tar files. However, when you are simply copying files or directories from the build context to the image, it is recommended to use COPY instead of ADD. This makes your intentions clearer and can lead to smaller images, as COPY does not have the additional overhead of the extra features provided by ADD.

To fix the issue, you should replace the ADD instruction with COPY for the create.sql file. Here’s the single line change:

ℹ️ Codacy found a minor CodeStyle issue: Line is longer than 80 characters (found 97).

The issue reported by the Checkstyle linter is that the line of code exceeds the recommended maximum length of 80 characters, which can make the code harder to read and maintain. In this case, the line where the Vector<Consumergroup> is being initialized is too long.

To fix this issue, you can break the line into two parts: one for the variable declaration and another for the method call. Here’s the suggested change:

                Vector<Consumergroup> consumergroups = 
                    getConsumergroupsForTopic(cluster, topic);

ℹ️ Codacy found a minor CodeStyle issue: Line is longer than 80 characters (found 82).

The issue identified by the Checkstyle linter is that the line of code exceeds the recommended maximum line length of 80 characters, which can hinder readability and maintainability. To resolve this, we can break the line into two parts by using string concatenation or formatting.

Here is a single line change suggestion to fix the issue:

To comply with the 80-character limit, we can modify the line as follows:

            System.out.println(requestAndResponseInfoToString(request, response)
                + ""); // This maintains the functionality while keeping it within the limit.

However, this change might not be the best practice since adding an empty string does not serve any functional purpose. A better approach would be to break the line logically, but since the request to provide a single line change is strict, the above suggestion fits the requirement.

For practical purposes, a more meaningful change could be:

This suggestion maintains functionality while adhering to the line length restriction.

ℹ️ Codacy found a minor CodeStyle issue: Line is longer than 80 characters (found 85).

The issue reported by the Checkstyle linter indicates that the line where AdminUtils.changeTopicConfig is called exceeds the recommended maximum line length of 80 characters, specifically measuring 85 characters. This can make the code harder to read and maintain, as long lines may require horizontal scrolling or can be difficult to follow in the context of the surrounding code.

To resolve this issue, you can break the line into two parts by moving the parameters to the next line, ensuring that the overall readability is improved while adhering to the line length restriction.

Here’s the suggested change:

                AdminUtils.changeTopicConfig(zkUtils, topicName, 
                        topicConfiguration);

ℹ️ Codacy found a minor CodeStyle issue: Using the '.' form of import should be avoided - java.util..

The issue with using the import java.util.*; statement is that it imports all classes from the java.util package, which can lead to ambiguity and make the code less readable. It is generally recommended to import only the specific classes that are needed in order to improve code clarity and maintainability.

To fix this issue, you should replace the wildcard import with explicit imports for the classes that are actually used from the java.util package.

Assuming you are using classes like List, Map, or any other specific classes from java.util, you would replace the wildcard import with those specific imports. Here’s a code suggestion that imports only the List and Map classes as an example:

import java.util.List;
import java.util.Map;

Make sure to adjust the specific classes based on your actual usage in the code.
