Как выполнить запрос к представлению в Hive?

0 голосов
/ 15 января 2019

Мы выполняем простой выбор в представлении (которое содержит много данных), и мы получаем «Превышен предел накладных расходов GC из-за ошибки памяти. Мы хотим выполнить этот запрос, чтобы отчет, который запускался поверх этого представления может работать. Работает на Tez.

Запрос выполняется в течение 4+ часов и завершается неудачно. Есть ли способ, которым мы можем выполнить этот запрос, например, некоторые параметры?

Запрос

Согласно журналу, исключение составляет OutOfMemoryError: GC overhead limit exceeded в MapJoin HashTableLoader.

проверить текущие настройки и соответственно увеличить: 

set hive.tez.container.size=4096MB; 
set hive.auto.convert.join.noconditionaltask.size=1370MB --recommended one third of container size

Попробуйте использовать оптимизированную для памяти хеш-таблицу: 

set hive.mapjoin.optimized.hashtable=true;
set hive.mapjoin.optimized.hashtable.wbsize=10485760; --Default Value (10 * 1024 * 1024)
--Optimized hashtable uses a chain of buffers to store data. This is one buffer size.

Наконец, если ничего не помогает, вы можете отключить mapjoin: 

set hive.auto.convert.join=false;
...
