@Jonas Straub @Vedant Jain Hi! I'm having similar issues.. I have a cluster running on 8 ec2 instances. I had to change the 'login as' to 'ec2-user' instead of 'root' when I used Ambari server to setup since ssh over root was giving me error.. Now I have 2 questions: - Since ambari did not use root, does that mean some env variables were not set by ambari? (I had no errors installing everything) - I can see jdk64 folder installed but its not in path.. So I cannot use 'java' commands.. Does that mean I have to go to every instance and do `export JAVA_HOME=/usr/jdk64/jdk1.8.0_40/bin/java` on every instance ? 😞 - Even after I set JAVA_HOME, I am unable to use 'jre' which I need for executing storm code!! What should I do?? ... View more
