----------------------------------------
Summary: Reduced memory overhead of TestBPOfferService
Key: HDFS-17605
URL: https://issues.apache.org/jira/browse/HDFS-17605
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
With default memory settings TestBPOfferService often errors with GC overhead /
OOM errors. After analysing the heap dump, this is due to Mockito holding lots
of references to invocations on a datanode mock.
This mock is never checked for invocations so we can mark it as stubonly and
allow Mockito to drop the invocations. This small change allows the test to
consistently pass on my local environment.
