Parsing DNS response Answer section doesn't give expected results

Asked 2022-Apr-04 at 15:33

I'm trying to parse a DNS response using java. I'm following RFC-1035 for guidelines on how to send requests and receieve responses, the format that is.

According to said RFC the answer section of a response should look like so:

My problem is that I can't seem to parse the NAME in the answer section. It seems to start with a pointer which makes no sense.

I probably know at lot less about this than you but am wondering why you say that? firstByte is telling you there's a pointer and the following value (0x0c) shows you the offset of the name for compression purposes (if I've got that right). None of the other bits in the same byte as firstByte is set so that can be ignored from the point of view of the offset value

Jenkins/groovy: How to pretty-print a net.sf.json.JSONObject with null?

Asked 2022-Mar-31 at 11:16

Working on a Jenkins pipeline, I observed what looks like infinite recursion causing a stack overflow when I use JsonOutput.toJson() on a net.sf.json.JSONObject that slurped a JSON string containing null.

The following minimal code demonstrates the problem:

Answered 2022-Mar-31 at 11:16

Can you sidestep this immediate problem by using readJSON's returnPojo: true parameter, thereby solving your overall task sooner?

Getting plain old nulls rather than net.sf.json.JSONNull objects really helped me today, though my problem involved producing CSV rather than using JsonOutput.

Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391

You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

How to run spark 3.2.0 on google dataproc?

Asked 2022-Mar-10 at 11:46

Currently, google dataproc does not have spark 3.2.0 as an image. The latest available is 3.1.2. I want to use the pandas on pyspark functionality that spark has released with 3.2.0.

I am doing the following steps to use spark 3.2.0

Created an environment 'pyspark' locally with pyspark 3.2.0 in it
Exported the environment yaml with conda env export > environment.yaml
Created a dataproc cluster with this environment.yaml. The cluster gets created correctly and the environment is available on master and all the workers
I then change environment variables. export SPARK_HOME=/opt/conda/miniconda3/envs/pyspark/lib/python3.9/site-packages/pyspark (to point to pyspark 3.2.0), export SPARK_CONF_DIR=/usr/lib/spark/conf (to use dataproc's config file) and, export PYSPARK_PYTHON=/opt/conda/miniconda3/envs/pyspark/bin/python (to make the environment packages available)

Now if I try to run the pyspark shell I get:

One can achieve this by:

Actually a bit more information and stacktrace would have helped in debugging the issue. As per the information provided above,

This exception happens when there is a mismatch in the kerberos credential. Then GSSException occurs and this message is generated.

In the give example, the problem is insufficient memory. Thus, running the garbage collector to free up memory might remedy this. But the call to System.gc() is only a suggestion to the JVM. It is not guaranteed that that the garbage collector frees any memory through this call.

So this approach is somewhat of a heuristic.

Calling a Java variadic function from C through the JNI

Asked 2021-Dec-22 at 21:06

I am currently working on creating some Java bindings for a C library I work on. One of our C-structs has a char buffer that is a file system path. After calling the C function, the buffer is correctly populated. I want to take the buffer and convert it to a java.nio.file.Path member on the Java object.

I am having some trouble however. I for some reason am generating a NullPointerException within C, and I can't really see the problem.

The way to create a java.nio.file.Path object is going through java.nio.file.Paths::get().

Here is the relevant C code:

...

ANSWER

Answered 2021-Dec-22 at 21:06

The method you are trying to invoke is declared as get(String first, String... more). The variadic syntax in Java is just sugar for an array of the specified type, i.e. the two arguments of this method are really String and String[] -- which you correctly coded in the GetStaticMethodID call as (Ljava/lang/String;[Ljava/lang/String;).

So to call it you need two arguments: one String and one String[] (array) -- and (for your case) the array must contain zero elements, but such an empty array is not the same as NULL. Have a gander at NewObjectArray.

I had the same problem. On the startup of the amazon linux 2, there is a security patch that is installed.

The package causing the problem is log4j-cve-2021-44228-hotpatch.noarch (you can check that in /var/log/yum.log)

A temporary solution is to uninstall the patch and install another java version.
