外壳脚本中的配置单元查询

Question

I want to run the hive query inside the shell script. I want to exit shell script and throw error if my hive query fails. Right now, even if my hive query fails, the next steps are getting executed. can someone help with this:

val= hive -e " select col1 from table_name;" (assuming the table has only one row)

echo "don't run if hive fails"

Answer 1

hive -e "select col1 from table_name"

if test $? -ne 0
then 
    exit 1
