Hi Vlad,

I think you might be on to something.  File a JIRA?

It should be a simple improvement, I think.

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.
