Jinfeng, My build node has no readme in the folder with *.proto (protocol/src/main/protobuf). However, there's a readme.txt 3 levels up in "protocol", which I did not notice because I ran protoc manually (using Cygwin shell) in protocol/src/main/protobuf. IDEA debugger did help me to see the nature of the exception (which was neither caught nor logged), which pointed to protobuf.
The biggest problem I've been having with IDEA debugger is that some breakpoints don't fire, like any breakpoint I set in this class within ExprsesionTreeMaterializer.java: private static class MaterializeVisitor extends AbstractExprVisitor<LogicalExpression, FunctionLookupContext, RuntimeException> If I set a breakpoint in a function elsewhere that is called from within that private static class, the debugger won't even let me look at the source code for the stack frame in that private static class. All of this might be an IDEA bug, or perhaps there's some build setting to modify (doubtful). Everything involving the new VarDecimal type is now running much, much better. I've changed quite a few of the Cast-related functions to get it to compile, but it's still failing to run a query as below. What am I missing? 0: jdbc:drill:zk=local> select employee_id, salary, commission_pct from dfs.`c:/ apache/drill-master/drill/exec/java-exec/src/test/resources/parquet/varlenDecima l.parquet` where employee_id=100; SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

Actually, it was the first time I found this readme file yesterday, thanks to IDEA. When I modified Types.proto (which I have not done so before), IDEA lists this readme file not far away from Types.proto. That's how I end up with reading this file. Speaking about debugger used Drill, the IDEA debugger works fine for me normally. However, if you modify the freemarker template (which Drill uses to "staticly" generate a set of java source code in maven build time), then you need run "mvn install -DskipTests" or "mvn generate-sources" to make sure the change in template generates new source code, before start debugging code in IDEA.
