105. Hiveの動的ParPPonの上限
ParPPon数の上限がデフォで1000なので、
SET
hive.exec.dynamic.parPPon=true;
SET
hive.exec.dynamic.parPPon.mode=nonstrict;
SET
hive.exec.max.dynamic.parPPons=1000000;
SET
hive.exec.max.dynamic.parPPons.pernode=1000000;
SET
hive.exec.max.created.files=15000000;
みたいにして増やしておく必要がある
(数は適当。デメリット等は不明。単に増えると遅いのだ
と思う)
