------------------------------------
Assignee: Karan Mehta
> Row for "SYSTEM" schema is not created during ConnectionQueryServicesImpl
> init
> -------------------------------------------------------------------------------
>
> Key: PHOENIX-4227
> URL: https://issues.apache.org/jira/browse/PHOENIX-4227
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.12.0
> Reporter: Karan Mehta
> Assignee: Karan Mehta
>
> For every new schema created through Phoenix, a row containing the schema
> name (with a 0x0 at the beginning and the end) is added to SYSTEM.CATALOG
> table. This is used for by other statements such as "USE SCHEMA" or "CREATE
> SCHEMA" to determine if the schema exists or not.
> However when we turn on namespaces, SYSTEM tables are automatically migrated
> to SYSTEM namespace in HBase. However an SYSTEM.CATALOG entry with the row
> (\x0SYSTEM\x0) is not created. Thus other statements trying to use it might
> receive a SCHEMA_NOT_FOUND_EXCEPTION even though the schema exists in the
> file.
> A "CREATE SCHEMA SYSTEM" statement can create the corresponding row entry in
> the SYSCAT table. This JIRA is to fix this behaviour and make it consistent
> for all schemas across Phoenix.
