Subject Re: [VOTE] Release Apache Flink 0.10.0 (release-0.10.0-rc0)
Date Thu, 22 Oct 2015 09:31:08 GMT
@Stephan: That's right, the detached mode is very useful for streaming
programs. Let's see if we can merge Sachin's pull request to give more
meaningful exceptions in case of user programs which are not
compatible with the detached execution mode.

@Vasia: That's a feature :) You can adjust the number of old jobs to
be kept by setting 'jobmanager.web.history' (default is 5).
