---------------------------------------
Summary: Add enum for cluster state
Key: IGNITE-12225
URL: https://issues.apache.org/jira/browse/IGNITE-12225
Project: Ignite
Issue Type: Improvement
Reporter: Sergey Antonov
Assignee: Sergey Antonov
Fix For: 2.8
We have 3 cluster states at the moment: inactive, active, read-only.
For getting current cluster state and changing them {{IgniteCluster}} has
methods:
* {{boolean active()}}, {{void active(boolean active)}} - for cluster
activation/deactivation
* {{boolean readOnly()}}, {{void readOnly(boolean readOnly)}} - for
enabling/disabling read-only mode.
Also we have control.sh commans for changing cluster state:
* {{--activate}}
* {{--deactivate}}
* {{--read-only-on}}
* {{--read-only-off}}
For me current API looks unuseful. My proposal:
# Create enum {{ClusterState}} with values {{ACTIVE}}, {{INACTIVE}},
{{READ-ONLY}}.
# Add methods to {{IgniteCluster}}:
## {{ClusterState state()}} returns current cluster state
## {{void state(ClusterState newState)}} changes cluster state to {{newState}}
state
## Mark as deprecated the following methods in {{IgniteCluster}}: {{boolean
active()}}, {{void active(boolean active)}},
## Add new command to control.sh: {{control.sh --set-state
(ACTIVE|INACTIVE|READ-ONLY)}}
## Add warn message that command is depricated in control.sh. Commands:
{{--activate}}, {{--deactivate}}, {{--read-only-on}}, {{--read-only-off}}
