-----------------------------------------
Summary: Request pool resolution ignores JNI errors
Key: IMPALA-15382
URL: https://issues.apache.org/jira/browse/IMPALA-15382
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Aleksandr Efimov
RequestPoolService::ResolveRequestPool() stores the status returned by
JniUtil::CallJniMethod() but does not check it before reading the result.
If the Java call throws while converting a user principal or resolving a pool,
the default result is read instead. The client can then receive a misleading
denied-access error with an empty resolved pool, while the original JNI error
is lost.
Return the JNI status before inspecting the result and add a backend regression
test that verifies a short-name conversion error is propagated.
