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

             Summary: variable expansion doesn't work in beeline-site.xml
                 Key: HIVE-22325
                 URL: https://issues.apache.org/jira/browse/HIVE-22325
             Project: Hive
          Issue Type: Bug
          Components: Beeline
    Affects Versions: 3.1.2
            Reporter: Allan Espinosa
            Assignee: Allan Espinosa


I have a default jdbc connection string and I want to build on top on it to have customized connections like setting custom queue names.  

{code}
$ cat .beeline/beeline-site.xml
  <configuration  xmlns:xi="http://www.w3.org/2001/XInclude">

    <property>
      <name>beeline.hs2.jdbc.url.base</name>
      <value>jdbc:hive2://localhost/</value>
    </property>

    <property>
      <name>beeline.hs2.jdbc.url.myqueue</name>
      <value>${beeline.hs2.jdbc.url.base}?tez.queue.name=myqueue</value>
    </property>
  </configuration>
$ beeline -c myqueue

Error in parsing jdbc url: ${beeline.hs2.jdbc.url.base}?tez.queue.name=myqueue from beeline-site.xml
Beeline version 3.1.0.3.1.0.0-78 by Apache Hive
beeline>
{code}

Relevant code is found in https://github.com/apache/hive/blob/master/beeline/src/java/org/apache/hive/beeline/hs2connection/BeelineSiteParser.java#L94

Entry<T,T>#getValue() skips the variable expansion .  Using Configuration#get(key) would make this work.
