Hi Vlad,

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

It should be a simple improvement, I think.

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.
