> 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}
