This leaves the user with a > less-than-ideal debug session since there are no useful diagnostic messages > sent to the client for this failure. In addition it crashes before > registering/unregistering with the RM and crashes without generating history, > so the proxy URL is not very useful and there's no archived configuration to > check to see what setting the AM was using when it encountered the error. > The AM should handle this error case more gracefully and treat the failure as > it does any other failed job, with a proper unregistration from the RM and > with history. -- This message was sent by Atlassian JIRA (v6.2#6252)
