---------------------------------------
Summary: Some FE tests failed by NullPointerException in
FileSystemUtil
Key: IMPALA-11699
URL: https://issues.apache.org/jira/browse/IMPALA-11699
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Quanlong Huang
Assignee: Quanlong Huang
IMPALA-11469 makes FileSystemUtil depend on BackendConfig.INSTANCE to get the
configured prefix list of ignored dirs. However, there are some FE tests that
can't assure BackendConfig.INSTANCE is initiated, which cause failures like
this:
