             Summary: Improve log messages when using an UDAF without the required classes defined in VDB
                 Key: TEIID-4756
                 URL: https://issues.jboss.org/browse/TEIID-4756
             Project: Teiid
          Issue Type: Enhancement
    Affects Versions: 9.1.2
         Environment: * WildFly 10
* Teiid 9.1.2
* CentOs 7
            Reporter: Pedro Inácio
            Assignee: Steven Hawkins


When using an _UDAF _in a _VDB_, the required *JAVA_CLASS *and *JAVA_METHOD *are specified in the _VDB_.

When for some reason the _JAVA_CLASS_ or _JAVA_METHOD_ do not exist in the library, the message from the system is quite imperceptible.

In the following log excerpt, _GlobalTitleRangeCheck_ class does not exist in the _jar _ _rangecreator_. The model name that is defining the _VIRTUAL FUNCTION_s is _RangeGroupConcat_. The _VDB_ name is _CountryServiceListVDB_.


{panel:title=Log excerpt}
DEBUG [org.teiid.RUNTIME] (Worker53_async-teiid-threads203)  TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata.

...

INFO  [org.teiid.RUNTIME] (Worker53_async-teiid-threads203)  TEIID40073 The metadata for the VDB CountryServiceListVDB.1 is loaded, however it is not valid. Check models for errors. Correct the metadata and re-deploy.

INFO  [org.teiid.RUNTIME.VDBLifeCycleListener] (Worker53_async-teiid-threads203)  TEIID40003 VDB CountryServiceListVDB.1 is set to FAILED
{panel}

As observed from the log excerpt, the only possible hint to know what the problem is with the _FAILED _deploy might be:

_model "RangeGroupConcat" Using translator null and connection null to load metadata._

But this is a normal logging message that doesn't have nothing to do with the real problem.

When putting the entire system logging _ALL_ levels, then is easy to see what the problem is:

{panel:title=Log excerpt}
DEBUG [org.teiid.RUNTIME] (Worker52_async-teiid-threads202)  TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata.

{panel}

Here it is observable what the real problem is:

_No local specification found for class com.truphone.teiid.udaf.GlobalTitleRangeCheck in Module "mnom.rangecreator:main"_

So, to avoid unnecessarily losing time to investigate what the problem is, the message that is currently in *TRACE *level should be in, at least, *INFO* level.
