--------------------------------------
Summary: NullPointerException thrown on Hive startup
Key: LOG4J2-2881
URL: https://issues.apache.org/jira/browse/LOG4J2-2881
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.10.0
Reporter: Renukaprasad C
NPE thrown while starting hive in log4j. Not sure whether its concurrent/usage
issue . But throwing NPE is not good idea.
private ScheduledExecutorService getExecutorService() {
if (executorService == null) {
if (scheduledItems > 0) {
Here First condition is true and second condition is false. Which lead to NULL
executorService.
Below is the exception stack
