Karl Nelson created DRILL-7850:
----------------------------------
Summary: Drill class fails reflection resulting in
ClassNotFoundException
Key: DRILL-7850
URL: https://issues.apache.org/jira/browse/DRILL-7850
Project: Apache Drill
Issue Type: Bug
Components: Client - Java
Affects Versions: 1.18.0
Reporter: Karl Nelson
In a recent issue request on JPype it was reported that Apache Drill fails
under JPype. After a bit of tracing it appears that it is not a JPype issue,
but something in the Apache Drill jar that is preventing normal Java reflection
from operating on the classes in drill. In order for Python to operate on a
class it must first probe the class with getMethods. In this case an internal
class was returned and when probed it is triggering a Java error. As there
isn't much that I can do about internal errors generated by a 3rd party jar, I
need to bounce the issue back to the drill developers.
Replication instructions are on the github issue tracker.
[https://github.com/jpype-project/jpype/issues/913]
Current it is still possible to run Apache Drill with Python as the error can
be bypassed by loading the jar file twice. But a recent change to JPype to
correct a related issue with unresolved classes will make it a fatal error in
the next version.
