public class WhitelistBlacklist
extends Object
implements Serializable

A whitelist / blacklist implementation for filtering Hive tables. It can be configured as case-insensitive(ignoreCase = true) or case-sensitive(ignoreCase = false). By default, it's case-insensitive.

Parses input whitelist and blacklist of the form [dbpattern.tablepattern1|tablepattern2|...],... and filters accordingly. The db and table patterns accept "*" characters. Each of whitelist and blacklist is a list of patterns. For a table to be accepted, it must fail the blacklist filter and pass the whitelist filter. Empty whitelist or blacklist are noops.

Example whitelist and blacklist patterns:

db1.table1 -> only db1.table1 passes. db1 -> any table under db1 passes. db1.table* -> any table under db1 whose name satisfies the pattern table* passes. db* -> all tables from all databases whose names satisfy the pattern db* pass. db*.table* -> db and table must satisfy the patterns db* and table* respectively db1.table1,db2.table2 -> combine expressions for different databases with comma. db1.table1|table2 -> combine expressions for same database with "|".
