------------------------------------------
Summary: Minor cleanups to ShortCircuitReplica, FsDatasetCache,
and DomainSocketWatcher
Key: HDFS-5940
URL: https://issues.apache.org/jira/browse/HDFS-5940
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 2.4.0
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
ShortCircuitReplica#Key and FsDatasetCache#Key are pretty much identical code
and should be factored out to an external class. (There will soon be a need
for a third user of such an identifier.)
Another minor cleanup is that DomainSocketWatcher should not implement Thread.
It contains a thread currently, but I forgot to remove the "extends".
