----------------------------------

             Summary: Variable substitution broken when a query is contained in double quotes
                 Key: HIVE-10034
                 URL: https://issues.apache.org/jira/browse/HIVE-10034
             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 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}
NoViableAltException(83@[])

FAILED: ParseException line 1:1 cannot recognize input near 'describe' '<EOF>' '<EOF>'

{code}

This behaviour is a bit confusing, since cli accepts double quoted strings in other cases.
