But we will always > schedule a RMP when master starting up, so we still need to make sure that > there is no race between this RMP and other RMPs and SCPs scheduled before > the master restarts. > Please see [#[accompanying design document > |https://docs.google.com/document/d/1_872oHzrhJq4ck7f6zmp1J--zMhsIFvXSZyX1Mxg5MA/edit#heading=h.xy1z4alsq7uy] > ]where we call out the problem being addressed by this issue in more detail > and in which we describe our new approach to Master startup. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
