Rohini Palaniswamy commented on PIG-4603: ----------------------------------------- [~gvsmirnov], This is a good find. Do you want to work on this? If not I can take it up. > Classloader leak in SpillableMemoryManager > ------------------------------------------ > > Key: PIG-4603 > URL: https://issues.apache.org/jira/browse/PIG-4603 > Project: Pig > Issue Type: Bug > Affects Versions: 0.15.0 > Reporter: Gleb Smirnov > > In the constructor of {{SpillableMemoryManager}}, a {{NotificationListener}} > is added to the {{MemoryMXBean}}. This listener is never removed, even if the > application is re-deployed. > This results in the instance {{SpillableMemoryManager}} being still reachable > after a redeploy. This results in its class being reachable, which results in > the classloader being reachable, along with all the classes in it. > This leads to metaspace OutOfMemoryErrors. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
