> Missing source code from UDF causes drillbit startup to fail

> Project: Apache Drill
> Issue Type: Bug
> Reporter: Steven Phillips
> Assignee: Xiao Meng
>
> 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.

> 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.
