These aren't in 1.x, but new stuff in 2.x, which means that this behaviour is a regression. > In my tests I see that starting second instance of MiniDFSCluster > invalidates the first instance if I don’t change cluster base directory > (existing data directory is fully deleted), but at the same time static > declaration of getBlockFile and getStorageDirPath does not allow base > directory to be changed without affecting functionality. > This is a regression. for 1.0 you can change dir by setting the relevant data directory "test.build.dir". I don't see any reason why the static stuff is really needed, it's used in various tests, but that could be changed -especially as the static methods aren't in 1.x. Why not file a JIRA -and perhaps a patch?
