I have opened a pull request to address this issue by excluding the legacy JARs
from the ambari-server assembly descriptor. The PR adds `<excludes>` to prevent
ehcache 2.x, Jersey 1.x, and JAX-RS 1.x JARs (which are brought transitively by
dependencies like Hadoop and swagger-jaxrs) from being packaged, eliminating
the need for manual post-installation cleanup and preventing runtime classpath
conflicts.
