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

             Summary: Should not need to initialize a jdbc:calcite driver to 
make a RelBuilder
                 Key: CALCITE-4760
                 URL: https://issues.apache.org/jira/browse/CALCITE-4760
             Project: Calcite
          Issue Type: Improvement
            Reporter: Steven Talbot


We just tracked down a nasty issue with Calcite being shaded as a dependency in 
our code that could cause a stack like

 
{noformat}
No suitable driver found for jdbc:calcite: 
org/apache/calcite/tools/Frameworks.java:184:in withPrepare 
org/apache/calcite/tools/RelBuilder.java:225:in create
{noformat}
{{}}

{{}}

when calling RelBuilder.create.

Our fault ultimately, but [~julianhyde] pointed out that Calcite really 
shouldn't be trying to make a JDBC connection here.
