Billie Rinaldi commented on YARN-7447:
--------------------------------------
We don't need reflection to load YarnJacksonJaxbJsonProvider, since it is
already available with the hadoop-yarn-common dependency. I am not sure if
using this provider will change the behavior of other RMWebApp endpoints.
> Fix a couple of issues in services REST API

> [[email protected]] brought to my attention that creating a service
> through the REST API does not work unless yarn app -enableFastLaunch has
> previously been called. This is because we need to set the -Dservice.libdir
> property for the RM daemon.
> Another difference between the REST API behavior and the CLI is that posting
> the http or http-no-dns example json fails with the following, even though
> these examples work through the CLI:
> {noformat}
> {"diagnostics":"For TEMPLATE format, either src_file must be specified in
> ConfigFile, or the \"content\" key must be specified in the properties field
> of ConfigFile. "}
> {noformat}
