> TestSnapshotFromMaster#testSnapshotHFileArchiving assumes that all hfiles will be compacted
and be moved to “archive folder” after cleaning. But not all hfiles will be compacted
if there are large number of hfiles.
> The above may be happened if changing the default config like smaller write buffer(hbase.client.write.buffer)
or ExponentialClientBackoffPolicy.
> {code:title=TestSnapshotFromMaster.java|borderStyle=solid}
> // it should also check the hfiles in the normal path (/hbase/data/default/...)
> public void testSnapshotHFileArchiving() throws Exception {
>   //...
>   // get the archived files for the table
>     Collection<String> files = getArchivedHFiles(archiveDir, rootDir, fs, TABLE_NAME);
>     // and make sure that there is a proper subset
>     for (String fileName : snapshotHFiles) {
>       assertTrue("Archived hfiles " + files + " is missing snapshot file:" + fileName,
>         files.contains(fileName));
>     }
>   //...
> }   
> {code}
