### Question:
HTableNameConverter { public static String getSysConfigTablePrefix(String prefix) { return prefix + "_" + NamespaceId.SYSTEM.getNamespace() + ":"; } private  HTableNameConverter(); static String encodeHBaseEntity(String entityName); static String toHBaseTableName(String tablePrefix, TableId tableId); static String getSysConfigTablePrefix(String prefix); static String getSystemNamespace(String prefix); static TableId from(HTableDescriptor htd); static TableName toTableName(String tablePrefix, TableId tableId);  }### Answer:
@Test public void testGetSysConfigTablePrefix() throws Exception { CConfiguration cConf = CConfiguration.create(); String tablePrefix = cConf.get(Constants.Dataset.TABLE_PREFIX); Assert.assertEquals(tablePrefix + "_system:", HTableNameConverter.getSysConfigTablePrefix(tablePrefix)); }
