ContainerSafeModeRule Refactor
Currently, the Safemode Rule validation is driven by processing of reports sent by Datanodes, this is unnecessary and this also introduces additional complexity as the
ContainerSafeModeRuleis maintaining the same information that theContainerManageris maintaining.Since the information about
Containersare maintained at two different places, this can go out of sync and introduce bugs intoContainerSafeModeRulelogic. (eg: HDDS-5263)We will move to a simpler model where
ContainerSafeModeRulewill not care about report processing but checkContainerManagerto validate the rule.This is part-1 of the change where we introduce logic to use
ContainerManagerfor rule validation, this new logic is disabled by default (usingvalidateBasedOnReportProcessingflag). The new logic will be enabled once all theSafeModeRulesare updated with new logic.What is the link to the Apache JIRA
