Stefan Miklosovic commented on CASSANDRA-20448:
-----------------------------------------------
whole tool is very ... "basic" when it comes to argument parsing, there are
also tests (SSTableExpiredBlockersTest) which are pretty opinionated about how
arguments are parsed (e.g. testWrongArgsIgnored). It is not like I prefer this
too much but I am trying to incorporate it into what already exists to not
break anything else.

> A key reason to run sstableexpiredblockers is that you have disk space
> accumulating and you wish to investigate what's consuming the disk space.
> If size was included in the output (as shown below), it would make the output
> more useful. Generally, when you find a blocked expired table, the first step
> is to check what size it is to see if it's large enough to be a problem.
