kandi X-RAY | hannibal Summary
Hannibal is a tool to help monitor and maintain HBase-Clusters that are configured for manual splitting. While HBase provides metrics to monitor overall cluster health via JMX or Ganglia, it lacks the ability to monitor single regions in an easy way. This information is essential when your cluster is configured for manual splits, especially when the data growth is not uniform.

QUESTION
I'd like to know how to do 2 execution plans: "traditional" execution plan joins (A with B) and then C. The "new" plan joins (A with B) then (A with C) and then joins the result of those joins so there would be 3 joins. How would I code the traditional and new plan in Oracle SQLPlus given the code below? I also need to measure the time complexity of both methods to show that the new plan takes less time, which I believe I just do with set timer on; The joins can be on whatever attributes work. Same with select statements. I made a artist, b album, c track, and d played.
Here's the database:

Answered 2021-Apr-18 at 06:13Your question doesn't make a lot of sense, because it's imposing bizarre restrictions that we can't really assess, but I don't mind telling you how to join two joins
You already know how to join three tables in the normal/traditional/sensible sense. Here's how to join them as you ask:

QUESTION
This is kind of similar/related to my question here, but different enough to warrant a separate question.
When an array of GPS Coordinates are programmatically added to a Bing Map, I want to set the center of the map to the midpoint between all of the GPS coordinates in the array. For example, if I wanted to show Hannibal, Independence, Columbia, Jefferson City, and St. Louis (all in Missouri), the center should be around Columbia.
I imagine a way to do this might be to add all the latitudes and divide by the number of locations being marked (5 in the above case), and add all the longitudes and divide by that number also. The two averages could serve as the Center.
Is that a sensible way to compute the center coordinate, or is there a better way?
I want to do this in the code-behind (in C#).
UPDATEHere's my idea of what the (pseudo)code might be:
...ANSWER
Answered 2020-Dec-08 at 23:46It seems that the center of bounding box of the coordinates will work better for this task, because in this case points can fit the screen at the higher zoom level.
QUESTION
I want to write a function that, given a string, returns a new string in which occurences of a sequence of the same consonant with 2 or more elements are replaced with the same sequence except the first consonant - which should be replaced with the character 'm'
.
The explanation was probably very confusing, so here are some examples:
"hello world"
should return"hemlo world"
"Hannibal"
should return"Hamnibal"
"error"
should return"emror"
"although"
should return"although"
(returns the same string because none of the characters are repeated in a sequence)"bbb"
should return"mbb"
I looked into using regex but wasn't able to achieve what I wanted. Any help is appreciated.
Thank you in advance!

QUESTION
I've built an angular application with routing components. I've tried to add Facebook and Twitter sharing buttons. When navigating to other components through routerlinks, the Facebook and Twitter share buttons correctly update their URL. But when navigating to the same component that is already active with other route params, the Facebook sharing button updates the URL correctly, but the Twitter sharing button doesn't.
I've built a reproduction: https://github.com/MintPlayer/SocialShareButtonsAngular
- git clone https://github.com/MintPlayer/SocialShareButtonsAngular
- cd SocialShareButtonsAngular
- npm install
- ng serve --open
Now you can test it: - The upper share buttons are from the AppComponent. They won't change when navigating. - The bottom share buttons are located in the routing components, each time again to demonstrate what's happening
- Home
- From the homepage, click the bottom Facebook share
- The url to be shared is: u= https%3A%2F%2F....%2Fhome
- Click the bottom Tweet button
- The url to be shared is https://..../home
- All fine
- Go to John Wick
- From the John Wick page, click the bottom Facebook share
- The url to be shared is: u=https%3A%2F%2F....%2Fperson%2F1 (/person/1)
- Click the bottom Tweet button
- The url to be shared is https://..../person/1
- All fine
- Now navigate to another person (eg. Hannibal Lecter)
- From the John Wick page, click the bottom Facebook share
- The url to be shared is: u=https%3A%2F%2Fmintplayer.com%2Fperson%2F2 (/person/2)
- Click the bottom Tweet button
- The url to be shared is STILL https://..../person/1
- When switching between items rendered in the same navigation component, the Twitter sharing url isn't updating.
The entire reproduction can be found in this repository: https://github.com/MintPlayer/SocialShareButtonsAngular
There is essential information being printed to the console already.
Inside the FacebookShareComponent and TwitterShareComponent, there's a routerLink input. When the routerLink is being set, the commands array is being computed. The items inside this array are being monitored as well using the IterableDiffers.

Answered 2020-May-05 at 07:25I finally succeeded by just replacing the HTML back to the state required by the Twitter docs, and calling the widgets.load()
function.
QUESTION
I have this squid configuration file which is supposed to protect squid from unauthenticated access by using basic auth.
Squid runs as a docker service and I would like to grant unauthenticated access for all other docker services. I observed that the services operate in the network range 10.0.0.1 - 10.0.255.254 (according squid's access_log).
When I access squid from the internet, basic authentication works properly.
When I access squid from a service's shell, it is still asking for authentication. The expected outcome would be free passage. What am I missing?

To save code in the main space I've written some amateurish code in another class method, which i want to implement into my main method.

This is the code that I've written in the array class.
