----------------------------------------
Summary: hive-agent module fails all tests that trigger SLF4J
logger initialization due to conflicting SLF4J bindings on the test classpath
Key: RANGER-5664
URL: https://issues.apache.org/jira/browse/RANGER-5664
Project: Ranger
Issue Type: Bug
Components: Ranger
Reporter: Vyom Mani Tiwari
Assignee: Vyom Mani Tiwari
{{hive-agent/pom.xml}} declares {{org.slf4j:log4j-over-slf4j}} as a direct
test-scoped dependency, alongside {{slf4j-reload4j}} which is used as the
project's actual SLF4J binding. These two are mutually incompatible:
{{log4j-over-slf4j}} bridges legacy {{log4j}} API calls into SLF4J, while
{{slf4j-reload4j}} is an SLF4J binding that delegates back out to reload4j (a
log4j 1.2 fork). Having both on the classpath simultaneously creates a circular
delegation path, which SLF4J detects and deliberately fails fast on rather than
risk a {{{}StackOverflowError{}}}.
