Stefan Miklosovic commented on CASSANDRA-20448:
-----------------------------------------------
I will park this ticket for a while. We should do (1) first. I wanted to base
the parsing on classes / same logic we are using elsewhere and without (1) I
would do the same refactoring around "CmdLineOptions" as done in that PR. There
is a set of tools which are using CmdLineOptions already and doing the same
here and parsing it via "new GnuParser()" (again used at multiple places
already) is the cleanest way of doing this.

> 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.
