We are moving existing SAS Web tier from non-distributed environment to existing distributed environment( Hadoop cluster). we want to create same structure in distributed environment. What are the pre requisites or information do we need to do ? Could you please help me.
If you can share more details it would be helpful. You have mentioned that you will be moving web tier from non-distributed to distributed. How does this involve hadoop cluster?
Usually SAS web tier (also called mid-tier) has components like cache locator, web server, web application server, activemq. If your web tier shares the same server with any of the other SAS tier there could be additional components as well.
I think you should do a detailed impact analysis based on your current architecture and see what all changes you may have to perform for making this change.
