Description

When a new service is submitted through the YARN Services UI and an error occurs, the only message in the UI is

Error: Adapter operation failed

Even though the underlying REST API is returning one of the following messages, it is completely hidden from the end user

- \{"diagnostics":"Artifact tarball does not exist hbase-2.0.0.3.0.0.0.tar.gz"}
- \{"diagnostics":"Specified src_file does not exist on hdfs: hdfs-site.xml"}
- \{"diagnostics":"Failed to create service sleeper-service, because it already exists."}
