將腳本的輸出寫入配置單元中的文件

我有一個包含5個查詢集的腳本。我想執行該腳本並將輸出寫入文件。我應該從配置單元cli給出什麼命令。感謝將腳本的輸出寫入配置單元中的文件

使用INSERT從以前的帖子覆蓋最後查詢之前本地目錄「的localPath」 .. –

，我可以理解你對HIVE是新手，但是我的建議是從書本（某些編程配置單元）或網頁鏈接中瞭解它，嘗試一些東西，做研發，如果不是則提出請求。 –

樣本查詢文件（3個查詢）：

ramisetty @嚮往：〜/ my_tmp $ 貓queries.q

show databases; --query1 
use my_db; --query2 
INSERT OVERWRITE LOCAL DIRECTORY './outputLocalDir' --query3    
select * from students where branch = "ECE";  --query3

運行HIVE：

ramisetty @ aspire：〜/ my_tmp $ 配置單元

hive（默認）>source ./queries.q;

--output of Q1 on console-----

--output of Q2 on console -----
