The underlying exception causing the "Unable to instantiate java compiler" seems to be:
*Caused by: java.lang.ClassNotFoundException: No implementation of org.codehaus.commons.compiler is on the class path. Typically, you'd have 'janino.jar', or 'commons-compiler-jdk.jar', or both on the classpath.* * at org.codehaus.commons.compiler.CompilerFactoryFactory.getDefaultCompilerFactory(CompilerFactoryFactory.java:59)* * at org.apache.calcite.rel.metadata.JaninoRelMetadataProvider.compile(JaninoRelMetadataProvider.java:425)* I've tried to manually add the 'janino.jar' and 'commons-compiler-jdk.jar' jars as well as excluding them from the uber jdbc jar.
