Yusaku Sako, I've been learning about ember and how client side frameworks work only recently. We have a script we'd like to run with user input during ambari setup in order to prepare the nodes. We have three or four different LANs for each node, and the script makes sure we're using the right LAN and hostname on each node. This isn't a use case that makes sense for anyone but Unisys and our clusters.
So, I've added a step 3.5 to the install wizard in ambari-web which seems to work fine. However, it needs to give ambari-server the user input, have ambari-server save it to a file, and then wait for ambari-server to invoke and finish running the script. I've tried looking at how the other install wizard steps interact with ambari-server, but it doesn't make sense just yet. If you could let me know where to look in ambari-server, that would be help a lot.
