Async RATIS pipeline creation and destroy through heartbea… URL: https://github.com/apache/hadoop/pull/1469#issuecomment-536415974 > For SafeModeRules, I do modified the HealthyPipelineSafeModeRule a bit. Add two properties, one is "hdds.scm.safemode.pipeline.creation" to control whether create pipeline in safemode. Another is "hdds.scm.safemode.min.pipeline" control the minimum pipeline number to exit safe mode when create pipeline in safemode is enabled. @ChenSammi The problem is safe mode rules are only tracking the old pipelines. But since they are listening to OPEN_PIPELINE event any newly created pipeline is counted in the rule. So if we are waiting for 50 old pipelines and 20 new ones are created, rule would pass if just 30 old pipelines are reported. Therefore I think we need a way to separate the old pipelines from new ones in the rules. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
