[jira] [Updated] (PHOENIX-3166) Snapshot SYSTEM.CATALOG before performing upgrade

     [ https://issues.apache.org/jira/browse/PHOENIX-3166?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

James Taylor updated PHOENIX-3166:
----------------------------------
    Summary: Snapshot SYSTEM.CATALOG before performing upgrade  (was: Snapshot SYSTEM.CATALOG before upgrade run)

> Snapshot SYSTEM.CATALOG before performing upgrade
> -------------------------------------------------
>
>                 Key: PHOENIX-3166
>                 URL: https://issues.apache.org/jira/browse/PHOENIX-3166
>             Project: Phoenix
>          Issue Type: Bug
>            Reporter: James Taylor
>
> We should snapshot the SYSTEM.CATALOG before running the upgrade and restore to the snapshot in the event of a problem. Worst case, if connectivity to HBase goes down midway through the upgrade, we'll at least have the snapshot available to restore back in an emergency.
