Hi   I deployed CDH 5.4.8 on a 6 machine cluster (4 datanode, 1 namenode, 1 edgenode) with cloudera manager and parcels.   When launching `spark-shell` I get the following exception :   java.io.IOException: Cannot run program "/etc/hadoop/conf.cloudera.yarn/topology.py" (in directory "/home/sherloqq"): error=2, No such file or directory   When searching on this error I found the following two informations :   - It happens with Impala & Llama, deploying Yarn Gateways on the client nodes should fix it (here, third issue) - It's happened before and copying the `/etc/hadoop/conf.cloudera.yarn` fixes it but it's supposed to be fixed (here)   Adding a Yarn Gateway on the node with the Spark gateway didn't do anythig Copying the directory to the node did fix it, however it seems to be a temporary fix   Is there a better fix to this issue ?   Thanks   C. ...
