It may cause some deadlock since it's called inside StandaloneAppClient.ClientEndpoint.\r\n\r\nThis PR just changed CoarseGrainedSchedulerBackend.removeExecutor to be non-blocking. It's safe since the only two usages (StandaloneSchedulerBackend and YarnSchedulerEndpoint) don't need the return value).\r\n\r\n## How was this patch tested?\r\n\r\nJenkins unit tests.\r\n"},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/243623392","html_url":"https://github.com/apache/spark/pull/14882#issuecomment-243623392","issue_url":"https://api.github.com/repos/apache/spark/issues/14882","id":243623392,"user":{"login":"AmplabJenkins","id":4031291,"avatar_url":"https://avatars.githubusercontent.com/u/4031291?v=3","gravatar_id":"","url":"https://api.github.com/users/AmplabJenkins","html_url":"https://github.com/AmplabJenkins","followers_url":"https://api.github.com/users/AmplabJenkins/followers","following_url":"https://api.github.com/users/AmplabJenkins/following{/other_user}","gists_url":"https://api.github.com/users/AmplabJenkins/gists{/gist_id}","starred_url":"https://api.github.com/users/AmplabJenkins/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AmplabJenkins/subscriptions","organizations_url":"https://api.github.com/users/AmplabJenkins/orgs","repos_url":"https://api.github.com/users/AmplabJenkins/repos","events_url":"https://api.github.com/users/AmplabJenkins/events{/privacy}","received_events_url":"https://api.github.com/users/AmplabJenkins/received_events","type":"User","site_admin":false},"created_at":"2016-08-31T00:28:01Z","updated_at":"2016-08-31T00:28:01Z","body":"Merged build finished.
