hive中使用spark執行引擎的常用參數

set hive.execution.engine=spark;
set hive.exec.parallel=true;
set hive.exec.parallel.thread.number=8;
set hive.exec.compress.intermediate=true;
set hive.intermediate.compression.codec=org.apache.hadoop.io.compress.SnappyCodec;
set hive.intermediate.compression.type=BLOCK;
set hive.exec.compress.output=true;
set mapred.output.compression.codec=org.apache.hadoop.io.compress.GzipCodec;
set mapred.output.compression.type=BLOCK;

 

以上。
