Resolution: Fixed
> 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
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.5.0
>
>
> 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.
