[jira] [Commented] (SLIDER-83) RoleHistory to stop logging every released node in teardown

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLIDER-83?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14003115#comment-14003115 ] 

Steve Loughran commented on SLIDER-83:
--------------------------------------

The simplest solution here is to have a teardown mode -when set the {{maybeSaveHistory()}} code will not save its state.
The last state changed before teardown contains all the information needed to resume placement -which nodes were active at the time the state was saved. Logging that they were saved prior to teardown is irrelevant.
