Jimmy Xiang updated HBASE-10815: -------------------------------- Fix Version/s: 0.99.0 Status: Patch Available (was: Open) > Master regionserver should be rolling-upgradable > ------------------------------------------------ > > Key: HBASE-10815 > URL: https://issues.apache.org/jira/browse/HBASE-10815 > Project: HBase > Issue Type: Sub-task > Components: master, Region Assignment > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > Fix For: 0.99.0 > > Attachments: hbase-10815.patch > > > In HBASE-10569, two things could affect the rolling-upgrade from a 0.96+ > release: > * Master doesn't have its own info server any. It shares the same info server > with the regionserver. We can have a setting so that we can start two info > servers, one for the master on the original port, and one for the > regionserver. > * Backup master is a regionserver now. So it could hold regions. This could > affect some deployment. We can have a setting so that we can prevent backup > master from serving any region. -- This message was sent by Atlassian JIRA (v6.2#6252)
