Istvan Toth updated PHOENIX-7268:
---------------------------------
Summary: Namespace mapped system catalog table not snapshotted before
upgrade (was: Namespace mapped system tables are not snapshotted before
upgrade)
> Namespace mapped system catalog table not snapshotted before upgrade
> --------------------------------------------------------------------
>
> Key: PHOENIX-7268
> URL: https://issues.apache.org/jira/browse/PHOENIX-7268
> Project: Phoenix
> Issue Type: Bug
> Components: core
> Reporter: Istvan Toth
> Priority: Major
>
> When upgrading the system tables, Phoenix tries to take a snapshot of
> system.catalog.
> This is useful, as it provides a checkpoint that can be used to restore the
> previous state if the upgrade runs into problems.
> However, The Phoenix system table name is passed to HBase, which does not
> exist if system table namespace mapping is enabled.
> Either delay taking a snapshot until after we know if syscat is namespace
> mapped or not, or just try to take a snapshot of both possible HBase tables.
