> Currently HBaseStorageHandler doesn't provide mechanism for storage of binary sortable key and values. It is necessary when given HBase table is used for persistence by Apache Hive and Apache Phoenix. In that way all byte arrays read or written by Hive will be compatible with binary sortable format used in Phoenix.
> It turns out the major difference is in all numeric data types accordingly officially provided documentation - https://phoenix.apache.org/language/datatypes.html.
> That's how I'm using it in my code:
> {code}
>     private static String buildWithSerDeProperties(TableDescriptor tableDescriptor) {
>         Map<String, String> serdePropertiesMap = new HashMap<>();
>         serdePropertiesMap.put(HBaseSerDe.HBASE_TABLE_NAME, tableDescriptor.getTableName());
>         serdePropertiesMap.put(HBaseSerDe.HBASE_TABLE_DEFAULT_STORAGE_TYPE, BINARY_STORAGE_TYPE);
>         serdePropertiesMap.put(HBaseSerDe.HBASE_COLUMNS_MAPPING, buildHBaseColumnsDefinition(tableDescriptor));
>         serdePropertiesMap.put(HBaseSerDe.HBASE_VALUE_FACTORY_CLASS, PhoenixValueFactory.class.getName());
>         /* Use different key factory for simple and composite primary key */
>         if (tableDescriptor.getPkDescriptors().size() == 1) {
>             serdePropertiesMap.put(HBaseSerDe.HBASE_KEY_FACTORY_CLASS, PhoenixKeyFactory.class.getName());
>         } else {
>             serdePropertiesMap.put(HBaseSerDe.HBASE_COMPOSITE_KEY_FACTORY, PhoenixCompositeKeyFactory.class.getName());
>         }
>         String serDeProperties = serdePropertiesMap.entrySet().stream()
>                 .map(e -> quoteInSingleQuotes(e.getKey()) + " = " + quoteInSingleQuotes(e.getValue()))
>                 .collect(Collectors.joining(COLUMNS_SEPARATOR));
>         logger.debug("SERDEPROPERTIES are [{}]", serDeProperties);
>         return serDeProperties;
>     }
> {code}
