QUESTION
Due to the lack of activity of the library's GitHub site, I decide to drop this question here hoping for any support.
The problem I am working on is to read an Excel file in a streaming fashion. Specially, the Excel file is stored in a SQLite database, as blob, after being split into multiple rows using a certain block size. For example a 3MB file is split into three rows, each contains 1MB of raw data. Rows are property ordered, so if I pipe out the blob column of each row by order to the file system, I can get a copy of the Excel file.
Since StreamingReader
works with InputStream
, I decide to implement an InputStream
on top of those rows in the SQLite database, so that StreamingReader
reads data directly from the db.
I first construct a Sequence
on top of the query result, sequencing the bytes from all the blob columns:

QUESTION
everyone,
I have written a lambda in Node.js that takes a folder and zips its contents. To do this I used the Archiver library: Archiver
The following is my code to create the File:
...ANSWER
Answered 2022-Feb-17 at 15:52The problem is that you are not being able to zip your files properly, this can occurs by many issues, including:
- You are not waiting the file to be processed, you need to use
.close()
event to do this. - You are not sending the correct path to the files or dirs to zipped, normally the files that you upload together with the lambda files on the root dir of your project stay on
/var/task/
on the Lambda dir system, so to send the correct file use__dirname + '/file.name'
- You are not appending correctly the files, check the
.file()
and.append()
methods if you are sending the files correctly
If you have the following Lambda structure:

I am trying to call an OWL API java program through terminal and it crashes, while the exact same code is running ok when I run it in IntelliJ.
The exception that rises in my main code is this:
...ANSWER
Answered 2022-Jan-31 at 10:43As can be seen in the comments of the post, my problem is fixed, so I thought I'd collect a closing answer here to not leave the post pending.
The actual solution: As explained here nicely by @UninformedUser, the issue was that I had conflicting maven package versions in my dependencies. Bringing everything in sync with each other solved the issue.
Incidental solution: As I wrote in the comments above, specifically defining 3.3.0
for the maven-assembly-plugin
happened to solve the issue. But this was only chance, as explained here by @Ignazio, just because the order of "assembling" things changed, overwriting the conflicting package.
Huge thanks to both for the help.

QUESTION
I was compiling Apache Ranger following the steps from offcial webstie and encounter below error. Can anyone help to deal with this issue?
The Ranger version: 2.2-release.
...ANSWER
Answered 2022-Jan-13 at 09:11This seems to be some File system error more than maven issue, check if your disk has enough space to / you have the correct permissions to complete the build. Usually when I am building ranger this works for me the fastest and best.
QUESTION
I'm trying to restore dump files from locations that contain character from other languages besides English.
So here is what I did:
From inside the pgadmin
I used the backup tool like:
And inside the FileName
input provided an actual real folder named "א":
C:\א\toc.dump
The actual file argument (-f file
) has been auto decoded into:
pg_dump.exe --file "C:\\0F04~1\\TOC~1.DUM"
My question is what is the decoding system pgadmin uses in order to decode the file path argument?
How did it came up with 0F04~1
from א
?
I'm asking it because pg_restore is not supporting file path that contains not English chars (from cmd):
...ANSWER
Answered 2022-Jan-04 at 01:01This is not something weird pgadmin does, but rather it is something weird Windows itself does when needing to represent such file names in a DOS-like setting. Like when the name is more than 8 chars, or extension more than 3.
In my hands the weird presentation is only there in the logs and status messages. If I use the GUI file chooser, the file names look normal, and replay successfully.
If you really want to know what Windows is doing, I think that is a better question for superuser with a Windows tag. I don't know why you can't restore these files. Are you using the pgAdmin GUI file chooser or trying to type the names in directly to something?
QUESTION
I have the following Dockerfile
:
ANSWER
Answered 2021-Dec-05 at 23:05Does it make sense to iterate through layers like this and keep adding files (to some target, does not matter for now) and deleting the added files in case they are found with a .wh prefix? Or am I totally off and is there a much better way?
There is a much better way, you do not want to reimplement (with worse performances) what Docker already does. The main reason is that Docker uses a mount filesystem called overlay2
by default that allows the creation of images and containers leveraging the concepts of a Union Filesystem: lowerdir
, upperdir
, workdir
and mergeddir
.
What you might not expect is that you can reproduce an image or container building process using the mount
command available in almost any Unix-like machine.
I found a very interesting article that explains how the overlay storage system works and how Docker internally uses it, I highly recommend the reading.
Actually, if you have read the article, the solution is there: you can mount
the image data you have by docker inspect
ing its LowerDir
, UpperDir
, WorkDir
and by setting the merged dir to a custom path. To make the process simpler, you can run a script like:
QUESTION
I would like to host a model on Sagemaker using the new Serverless Inference.
I wrote my own container for inference and handler following several guides. These are the requirements:
...ANSWER
Answered 2021-Dec-14 at 09:30One possibility is that the serverless sagemaker version is trying to write the model in the same place that you have already wrote it in your inference container.
Maybe review your custom inference code and don't load the model there.

I'm new to modularized java 16 projects as well as using the maven build system whilst trying to implement the program using IntelliJ, JAVAFX and APACHE POI-OOXML.
For simplicity, I am implementing a button's event handler that instantiates a class that is responsible for using Apache: ControllerCode
The problem then happens here: line 24 of this code
Here is the stack trace:
...ANSWER
Answered 2021-Dec-12 at 05:38A piece as it says about a zip archive in the error. There is no actual stream assigned with the place e,g, you have a String path but analogous there is not actually so much as an actual .io.File related part of the code. There is however a constructor for such document that takes a Stream argument on construction.

I am new to java . I am using apache netbeans 12.2 version to create new project and the java version is 17 . I followed the step to create java web application with maven but when I build it and try to run it I am getting following errors in the console window.

Here is the Pom.xml code .
...ANSWER
Answered 2021-Dec-09 at 03:11Your version of Java is incompatible with your version of NetBeans because NetBeans 12.2 does not support the use of JDK 17. From the NetBeans 12.2 Release notes Downloading Apache NetBeans 12.2:
Apache NetBeans 12.2 runs on JDK LTS releases 8 and 11, as well as on JDK 15, i.e., the current JDK release at the time of this NetBeans release.
In general, when changing your version of NetBeans and/or Java, make sure that the versions are compatible. This is always documented in the NetBeans release notes.
You have two options to resolve this:
- Upgrade to NetBeans 12.6 which supports Java 17.
- Stay on NetBeans 12.2, but downgrade to Java 15 or lower. That is, make JDK 15 (or lower) your default platform for NetBeans 12.2.
Of course you may also have other issues with your project, but there is no point in worrying about those until you have fixed this problem.
