Description of problem: After installing hadoop-yarn, it does not work. I have tried it with the following applications: https://github.com/vector-im/riot-web#running-as-a-desktop-app https://github.com/wireapp/wire-desktop Removing the RPMs and installing yarn through npm is working. Version-Release number of selected component (if applicable): 2.7.7 How reproducible: Install hadoop-yarn and it's dependencies, try to start/build yarn application Steps to Reproduce: 1. Install hadoop-yarn 2. git clone above repos 3. start or build the application and see the error message
hadoop-yarn should not be misinterpreted as yarn as they don't exist for the same purpose. I made a report to port yarn (I'm working on porting Yarn to Cauldron), but until a Mageia package is released you can as a workaround install yarn by doing: npm install yarn Make sure you have npm installed before running it though.

And for the record, I'm also trying to port wire-desktop to Mageia. No package is built yet so please be patient.
yarn installed through npm does the job. Wire works perfectly on MGA, I am using it a long time ago, I installing the RPM I build.
@Tamás: See Kristoffer's Bug 24029 about Yarn. > installing yarn through npm is working > yarn could also be easily installed by executing > npm install --global yarn as root Kristoffer's work apart, Mageia does not currently offer straight 'yarn'. @Kristoffer: Thank you for your comments. > hadoop-yarn should not be misinterpreted as yarn as they don't exist for > the same purpose This suggests that trying to use 'hadoop-yarn' as 'yarn' is incorrect, they are not the same thing. True? If so, this bug is misguided.

According to the internet yarn is part of hadoop, but it seems it can be used standalone. Also in the past I have used hadoop-yarn and it worked like charm, so it can not be that different :)
Thank you for this last comment, and the clarification it brings about hadoop & its yarn. The package being hadoop-yarn-2.7.7-4.mga7. > in the past I have used hadoop-yarn and it worked like charm Was that Mageia's ?

Hi, Maybe the hadoop pkg was from mga7, but 2-3 weeks before I have opened the ticket, on cauldron/mga8 it was working.
hadoop was dropped for Cauldron!
Mageia7 is EOL and hadoop is no more provided, so closing as OLD.
