NullPointerException при запросе таблицы интеграции hive-hbase

0 голосов
/ 06 июля 2019

Я создал секционированную таблицу в hbase, используя интеграцию hive-hbase, и загрузил данные в эту таблицу, используя hive. Когда я пытаюсь выполнить любой запрос к этой таблице, я получаю исключение NullPointerException в map-Reduce. Другая интегрированная таблица hive-hbase работает нормально, но эта многораздельная таблица не работает.

запрос: 

select count(*) from partitioned_key_indicator_districtwise_hbase;

Ошибка:
