[jira] [Created] (HDDS-1239) Use chillmode state from
ChillModeManager in ChillModePrecheck
Nanda kumar created HDDS-1239:
---------------------------------
Summary: Use chillmode state from ChillModeManager in ChillModePrecheck
Key: HDDS-1239
URL: https://issues.apache.org/jira/browse/HDDS-1239
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: SCM
Affects Versions: 0.3.0
Reporter: Nanda kumar
Assignee: Nanda kumar
Currently {{ChillModePrecheck}} is instantiated in multiple places and it maintains its own state of chillmode. Because of this {{BlockManagerImpl}} and {{SCMClientProtocolServer}} listens to chillmode status event to update {{ChillModePrecheck}} that they maintain.
It will be easier if {{ChillModePrecheck}} queries {{SCMChillModeManager}} to get the current chillmode state. It will also make the code simple if {{SCMChillModeManager}} provides {{ChillModePrecheck}} instance, instead of everyone creating a new object of {{ChillModePrecheck}}.
