Re: javax.persistence.Persistence classNotFoundError

2016-05-02 Thread Ananth Gundabattula 
Hello Siyuan,

Please find attached the output of the unzip -t command on the apa package.

The library jar is indeed present in there.

What confuses me here is that the stack trace suggests that it is coming
when the engine is validating the App ( and not from my application code).
I am suspecting one of the following is causing this :


   - the bval ( JSR 303 ) jar validation path  is somehow conflicting with
   the JPA validation framework and is causing this issue but am not sure.
   - CDH 5.7 might have changed restructured a few jars ?? ( I am not sure
   of this either as I am not sure how Apex uses the underlying Hadoop
   distribution jars )

Pasting the stack trace once more here for reference:

An error occurred trying to launch the application. Server message:

Hey Ananth,

Can you unzip your apa file to see if it is in the lib folder? If it is not
there, it means the packaging is not correct.

Re: javax.persistence.Persistence classNotFoundError

2016-05-02 Thread Ananth Gundabattula 
Hello All,

I was able to get around the issue pasted above by manually copying the
javaee-api-7.0 jar inside the lib folder of Apex engine. It may be noted
that the code works perfectly fine in a unit test that launches all of the
operators in the DAG. ( Works end to end ) . However when I launch it on
CDH 5.7 I run into the exception pasted above. It may be noted that the
exception is being raised when I launch the app and the Apex engine is
trying to validate the newly deployed app.

I am suspecting that this could be an issue with incompatibility with CDH
5.7 ( The Hadoop stack on which I am trying to run Apex 3.3 on )

Could anyone help me if they were able to run Apex on top of CDH 5.7. I got
the same exception with both Apex 3.3 and 3.2.

Regards,
Ananth

javax.persistence.Persistence classNotFoundError

2016-04-29 Thread Ananth Gundabattula 
Hello All,

I am getting the following exception when I launch my Apex app.

I tried including javaee-api- version 7.0 as well to get around this error
but does not seem to take effect.

Any ideas why javax.persistence.Persistence is not getting loaded by the
APex engine classloader ?

An error occurred trying to launch the application. Server message:
