> Key: HDFS-5511
> URL: https://issues.apache.org/jira/browse/HDFS-5511
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: 3.0.0
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Fix For: 3.0.0
>
> Attachments: HDFS-5511.001.patch, HDFS-5511.002.patch
>
>
> The CacheManipulator interface has been helpful in allowing us to stub out
> {{mlock}} in cases where we don't want to test it. We should move the
> {{getMemlockLimit}} and {{getOperatingSystemPageSize}} functions into this
> interface as well so that we don't have to skip these tests on machines where
> these methods would ordinarily not work for us.
