Hi,
1. The image below shows 2 YARN instances using the same federation of
clouds. Is this possible?
2. I have configured in 2 hosts (hadooop-coc-1, and hadoop-coc-2) a
federation of HDFS. In the configuration, I have set a namespace in each
host, and a single data node (see image). The service is running
properly. You can check the output of the |jps| commands in [1].
The strange part is that, when I list the files, they do not appear in
hadoop-coc-2. You can check the output in [2]. Why this happens?
