---------------------------------
Summary: 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.
