> If the source file is not included when adding a UDF, drillbit fails to start up:
> Exception in thread "main" org.apache.drill.exec.exception.DrillbitStartupException: Failure during initial startup of Drillbit.
>   at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:75)
>   at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:59)
>   at org.apache.drill.exec.server.Drillbit.main(Drillbit.java:82)
> Caused by: java.lang.IllegalArgumentException: resource /com/tdunning/drill/exec/expr/fn/impl/HbaseLookup.java relative to com.tdunning.drill.exec.expr.fn.impl.HbaseLookup$Lookup not found.

>   at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:72)
> I think it would be better to allow the drillbit to startup, and put an error message in the log indicating that the UDF was not loaded, and how to resolve it.
> If anyone thinks it is better to fail drillbit startup in this case, please discuss.
