Andras Piros commented on OOZIE-1770:
-------------------------------------
* as for benchmark results I think for this JIRA the one that has already been
measured (some simple shell actions pre-OYA and OYA performance) would be fine,
for the deeper measurements we could open another JIRA.
* as for re-testing that property {{launcher.lib.*}} still works, I don't know
of an example workflow - [~rkanter] can you please advise?
* as for generated {{launcher.xml}} file content printouts, [~rkanter] can you
please also advise?
* as for {{ApplicationHistoryServer}} (former {{TimelineService}}) usage, the
patch hasn't changed the way of usage.
* as for {{JavaActionExecutor.setCredentialTokens()}}, here are the important
changes - none of which changes functionality, only making code more readable:
** some of the former {{CredentialsProvider}} is extracted to
{{CredentialsProviderFactory}}, some other parts of it are left in
{{CredentialsProvider}}
** {{CrendentialsProvider}} is now an {{interface}}, not an {{abstract class}}
** {{Credentials.addToJobConf()}} functionality is moved to different
{{CredentialsProvider.updateCredentials()}} implementations, and {{abstract
class Credentials}} has been removed
