             Summary: Hard code in JaninoRelMetadataProvider makes shading for Calcite failed
                 Key: CALCITE-1461
                 URL: https://issues.apache.org/jira/browse/CALCITE-1461
             Project: Calcite
          Issue Type: Bug
            Reporter: Jark Wu
            Assignee: Julian Hyde
             Fix For: 1.9.0


In {{JaninoRelMetadataProvider.load3}}, the generated class string contains some hard coded Calcite's classes, such as {{org.apache.calcite.rel.metadata.MetadataDef}}. After shading Calcite, the MetadataDef can not be found in the shaded classes. And a compile error will be thrown.

So it's better to use {{MetadataDef.class.getName()}} to replace the hard code string.

I'm appreciate to make a PR if you want.
