>
> Currently the Hadoop server components can't be started from IDE during the
> development. There are two reasons for that:
> 1. some artifacts are in provided scope which are definitelly needed to run
> the server (see HDFS-12197)
> 2. The src/main/webapp dir should be on the classpath (but not).
> In this issue I suggest to fix the second issue by reading the web resources
> (html and css files) directly from the source tree and not from the classpath
> but ONLY if the src/main/webapp dir exists. Similar approach exists in
> different projects (eg. in Spark).
> WIth this patch the web development of the web interfaces are significant
> easier as the result could be checked immediatelly with a running severt
> (without rebuild/restart). I used this patch during the development of the
> Ozone web interfaces.
> As the original behaviour of the resource location has not been change if
> "src/main/webapp" doesn't exist, I think it's quite safe. And the method is
> called only once during the creation of the HttpServer2 there is also no
> change in performance.
