----------------------------
Summary: Potential race condition on modification of
dirtyAttributeInfoCache in MetricsMBeanImpl#getMBeanInfo()
Key: HIVE-8927
URL: https://issues.apache.org/jira/browse/HIVE-8927
Project: Hive
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
{code}
public MBeanInfo getMBeanInfo() {
if (dirtyAttributeInfoCache) {
synchronized(metricsMap) {
attributeInfos = new MBeanAttributeInfo[metricsMap.size()];
{code}
The check of dirtyAttributeInfoCache is outside the synchronized block.
There is possibility that different attributeInfos are returned due to race
condition.
