[jira] [Commented] (HIVE-2226) Add API to retrieve table names by an arbitrary filter, e.g., by owner, retention, parameters, etc.

Summary
-------

Create a function listTableNamesByFilter that returns a list of names for tables in a database that match a certain filter. The syntax of the filter is similar to the one created by HIVE-1609. You can filter the table list based on owner, retention, or table parameter key/values. The filtering takes place at the JDO level for efficiency/speed.  Added a QueryFilterType enum to easily add new filters and separate logic for filtering.  

Example filter statements include: 
filterType = QueryFilterType.OWNER; filter = "owner like ".*test_user.*"
filterType = QueryFilterType.RETENTION; filter = "retention < 90 and retention > 30"
filterType = QueryFilterType.PARAMS; filter = "numPartitions = \"2\" and  retention_days = \"30\""

The filter can currently parse string or integer values, where values interpreted as strings must be in quotes.


This addresses bug HIVE-2226.

> Create a function called get_table_names_by_filter that returns a list of table names in a database that match a certain filter.  The filter should operate similar to the one HIVE-1609.  Initially, you should be able to prune the table list based on owner, retention, or table parameter key/values.  The filtering should take place at the JDO level for efficiency/speed.
