Hi, I was creating amazon ami from sandbox to launch ec2-instance. I followed all the above steps correctly with HDP 2.3.2 and 2.4 sandbox versions. I created an amazon ami but I was not able to get Hadoop running on ec2 instance. Even I was not able to access ambari server at port 8080. I tried changing hostname of ec2-instance to "sandbox.hortonworks.com", gave security groups open to all ports but no use. When I looked at the processes started after bootstrap, I found some process like HDFS, Mapred are not started in ec2-instace which are started in sandbox in virtual box. Can someone please help me in this? Thanks! ... View more
