I am trying to run the HBase shell. The shell get starts but when I put any command it gives me this error:

I'm using Scrapy and I'm having some problems while loop through a link.

I'm scraping the majority of information from one single page except one which points to another page.

There are 10 articles on each page. For each article I have to get the abstract which is on a second page. The correspondence between articles and abstracts is 1:1.

Here the divsection I'm using to scrape the data:

I am creating a JTable in Netbeans and am having three minor issues with the structure.

1. I can't seem to align my table in the direction I want (Say North, East, South, or West) and now it's annoyingly hovering over my JButton.
2. The code I wrote to set the dimensions of the JTable do nothing if I change the variables.
3. The code I wrote to add a JScrollPane is not showing up when I run it.

I understand if you can't solve all three but I figured I'd put them all in one instead of three different questions so any help with a problem is appreciated!

**Also as a note, ignore everything after the ActionListener. I am eventually going to make the code read a text file and sort that data in an ArrayList. Then somehow into the table instead of how I manually set it up in this example.

Here is my code (problem areas are labeled in comments in bold, capitalized font):

Main:

I've created a proof-of-concept SPA (source code / demo) which loads stereoscopic images from a web server and renders them in stereoscopic 3D using the aframe-stereo-component for A-frame.

Testing this on a Quest 2 in the Oculus Browser and Firefox Reality, this works fine: each image appears in 3D when viewed in immersive VR mode via WebXR.

However, after scrolling through a number of images (usually 8 to 12), the slideshow stops working. In Firefox Reality, this manifests by the app just freezing and becoming unresponsive.

In Oculus Browser, the image description is displayed but the image area remains black. Connecting the Quest 2 to a PC with adb and inspecting the page using Chrome DevTools, I can see the following output when this occurs:

I'm running my java application on apline linux system in docker container, and I wanna find out the value of MaxHeapSize, so I use several command : java -XX:+PrintFlagsFinal, jinfo -flag MaxHeapSize , jmap -heap, but the output made me feel confused. The output of jinfo -flag MaxHeapSize , jmap -heap are consistent. However, The output of java -XX:+PrintFlagsFinal is different.so why did this happen?

The default container memory Limit setting is 4096MiB.

The output of java commonds is shown below.(I marked some important parts in the picture)

Let's say I have a Jelastic manifest where, in the settings section, I ask the user for an email address (to setup some service). Because the user using Jelastic already is logged on Jelastic with an email, it might make sense to propose to the user that she uses that email. It saves her typing during the manifest setup. So, ideally, what I would like to do is this:

I am trying to set up distributed HBase on 3 nodes. I have already set up hadoop, YARN ZooKeeper and now HBase but when I launch hbase shell and run the simplest command for example status or list I get the exception:
