Trying to run docker image of hortonworks giving 0.0.0.0:2181 failed to port is already allocated



I am following hortonworks dockerization document from hortonworks and running below commands after downloading "HDP_2.6.5_deploy-scripts_180624d542a25.zip" file.



After extracts , I executed "docker-deploy-hdp265.sh" file.



It executes two commands
docker start sandbox-hdp
docker start sandbox-proxy



first one run perfectly and when I execute "docker start sandbox-proxy" it gives below error




Error response from daemon: driver failed programming external connectivity on endpoint sandbox-proxy (7d3f4a490fc3d782c36ba4bf35921a896acc3edf35d2bf4d9522aebfeea002f5): Error starting userland proxy: Bind for 0.0.0.0:2181 failed: port is already allocated
Error: failed to start containers: sandbox-proxy



please suggest what I am doing wrong,
I also, use this command to update host files




sudo echo '127.0.0.1 sandbox.hortonworks.com sandbox-hdp.hortonworks.com sandbox-hdf.hortonworks.com' | sudo tee -a
127.0.0.1 sandbox.hortonworks.com sandbox-hdp.hortonworks.com sandbox-hdf.hortonworks.c





Without knowing too much, I'd say that you probably have the port allocated, ie. used by another service. Try to figure out what ports are in use, maybe change the port used by the container, or stop the one running.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]&g
