nkeywal commented on HBASE-4639:
--------------------------------

Was actually implemented in HBASE-4634. On the tests mentioned above, on the central build, it brings the time from 4 minutes to 17 seconds.

> Some tests could go directly to the localsystem instead of using a DFS cluster. This speeds-up the test.
> TestScanner From 60s to 5s
> TestCompaction from 140s to 15s
> TestGetClosestAtOrBefore from 9s to 1s
> TestStoreFile from 30s to 2s
> TestWideScanner: 18s -> 3s
> TestFSTableDescriptorForceCreation 3s -> 1s
> There is a partial dependency with HBASE-4634, as we now write on localdisk the data is not freed when the test is over.
