> 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.
