Re: IllegalAccessError when writing to hive orc table

Hi Paul,

On the other hand, the flink runtime, which contains `
HadoopPathBasedBulkFormatBuilder ` is located in the lib folder. Since the
two jars are loaded by different class loaders, the classes are considered
under different packages. That’s why an `java.lang.IllegalAccessError`
occurred.

Thanks for your analysis, hive contains `HadoopPathBasedBulkFormatBuilder`
and runtime contains `DefaultBucketFactoryImpl`. Looks like it is dangerous
to use package constraints for different modules. It is better to use
public. CC: @Yun Gao

use https://repo.maven.apache.org/maven2/ instead?

Yes, we should use new URLs. I created
https://issues.apache.org/jira/browse/FLINK-18593 JIRA for tracking this.

Best,
Jingsong

Re: IllegalAccessError when writing to hive orc table

2020-07-13 Thread Paul Lam 
Hi Jingsong,

Thanks to your pointer, I checked the dependencies and found out that it’s 
caused by the classloaders.

In my deployment, the hive connector (and its orc dependencies), which contains 
`DefaultBucketFactoryImpl`, was packaged into the job uber jar.  On the other 
hand, the flink runtime, which contains `HadoopPathBasedBulkFormatBuilder ` is 
located in the lib folder. Since the two jars are loaded by different class 
loaders, the classes are considered under different packages. That’s why an 
`java.lang.IllegalAccessError` occurred.

BTW, the artifact links of the hive connectors seem to be broken. Should we use 
https://repo.maven.apache.org/maven2/  
instead?

Best,
Paul Lam

Hi, It looks really weird.

Is there any possibility of class conflict?
How do you manage your dependencies? Do you download bundle-jar to lib? [1]

IllegalAccessError when writing to hive orc table

2020-07-13 Thread Paul Lam 
Hi,

I’m trying out Flink 1.11 and trying to write data to Hive orc tables, but get 
stuck with a weird exception. Wonder if anyone had met this before?  The Java 
version is 1.8.0_151.
