[jira] [Updated] (SLIDER-226) Provide mechanism for rolling upgrade
[ https://issues.apache.org/jira/browse/SLIDER-226?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Yu updated SLIDER-226:
--------------------------
Description:
build action paves the road for supporting rolling upgrade on Slider deployed cluster.
User can specify a different image for a running cluster with N instances for role R.
The rolling upgrade would restart each of the N instances while maintaining the invariant that there're at least N-1 active instances for role R.
After restart, new image would be effective.
This capability would, e.g., allow HBase to perform compatibility check across releases.
