----------------------------------------

Any update to this issue? Considering how long it has been open, is it still a concern?

> Minor compactions add files to !METADATA table and then update the tablets in memory
list of files.  Major compactions do the opposite, update in memory list then !METADATA. 
In the case of machine failures, this could lead to a user see the result of major compaction
iterators and then not seeing it.  Minor compactions do not have this issue.  See ACCUMULO-6
