Akshita Malhotra commented on PHOENIX-3475:
-------------------------------------------
Thanks [~jamestaylor]
Both the solutions give us just the name of the base index table. We require
additional Phoenix metadata to construct table descriptor. Also using
DatabaseMetadats #getTables() to retrieve all index types is undesirable as it
returns views whose names don't map to an HBase table. Moreover, it still
doesn't return view indexes.
In all, the task is to retrieve complete Phoenix metadata corresponding to a
physical view index table (not just the name).

> Key: PHOENIX-3475
> URL: https://issues.apache.org/jira/browse/PHOENIX-3475
> Project: Phoenix
> Issue Type: Bug
> Reporter: Akshita Malhotra
> Fix For: 4.9.0
>
>
> HBase migration tool uses DatabaseMetadata#getTables() API to retrieve the
> tables for copying data. We have found that API doesn't return base index
> tables ( _IDX_<base table name>)
> For testing purposes, we issue following DDL to generate the view and the
> corresponding view index:
> -CREATE VIEW IF NOT EXISTS MIGRATIONTEST_VIEW (OLD_VALUE_VIEW varchar) AS
> SELECT * FROM MIGRATIONTEST WHERE OLD_VALUE like 'E%'
> -CREATE INDEX IF NOT EXISTS MIGRATIONTEST_VIEW_IDX ON MIGRATIONTEST_VIEW
> (OLD_VALUE_VIEW)
> By using HBase API, we were able to confirm that base index table
> (_IDX_MIGRATIONTEST) is created.
> Both jdbc DatabaseMetadata API and P* getMetaDataCache API doesn't seem to
> be returning view indexes. Also P*MetaData #getTableRef API return
> "TableNotFoundException" when attempted to fetch PTable corresponding to the
> base index table name.
