通过将表名作为参数并执行hive查询来编写shell脚本

Question

我正在尝试构建一个以table_name作为参数的shell脚本，然后运行以下的hive查询。

INSERT OVERWRITE DIRECTORY '/data/table_name' 
row format delimited
FIELDS TERMINATED BY ','
SELECT * FROM table_name

Answer 1

也许你需要它：

#!/bin/bash
if [ -z "$1" ]; then exit 1; fi    
printf -v TAB "%q" "$1"
/usr/bin/mysql -NBe "INSERT OVERWRITE DIRECTORY '/data/table_$TAB' row format delimited FIELDS TERMINATED BY ',' SELECT * FROM $TAB"
