> TestHFileArchiving#testCleaningRace creates HFileCleaner instance within the
> test.
> When SnapshotHFileCleaner.init() is called, there is no master parameter
> passed in {{params}}.
> When the chore runs the cleaner during the test, NPE comes out of this line
> in getDeletableFiles():
> {code}
> return cache.getUnreferencedFiles(files, master.getSnapshotManager());
> {code}
> since master is null.
> We should either check for the null master or, pass master instance properly
> when constructing the cleaner instance.
