-----------------------------------------
Summary: MetaData #getTables() API doesn't return view indexes
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.
