Sergey Shelukhin commented on HIVE-10034:
-----------------------------------------
I suspect this is not a HIVE problem - $blah is bash syntax for variables, so
bash is replacing ${a} in double-quoted string before command gets to hive.
Can you try to echo the same string with both types of quotes?

> Project: Hive
> Issue Type: Bug
> Components: CLI
> Affects Versions: 0.13.1
> Environment: Ubuntu 12.04.5 LTS
> Reporter: Jakub Kukul
> Priority: Minor
>
> Variable substitution works fine when a SQL passed from the command line is a
> single quoted string:
> {code}
> hive --hivevar a=b -e 'create table if not exists b (col int); describe ${a}'
> {code}
> , but when the query string is contained within double quotes:
> {code}
> hive --hivevar a=b -e "create table if not exists b (col int); describe ${a}"
> {code}
> it fails with the following stack:
> {code}
