Jeff Jirsa commented on CASSANDRA-5791:
---------------------------------------

Since [~benedict] pulled in CASSANDRA-8778 (thanks Benedict!), I've rebased to 
exclude that patch from this change set, added unit tests, and collapsed all 
requested changes into a single commit for easy merging.

> CUrrently there is no nodetool command to validate all sstables on disk. The 
> only way to do this is to run a repair and see if it succeeds. But we cannot 
> repair the system keyspace. 
> Also we can run upgrade sstables but that re writes all the sstables. 
> This command should check the hash of all sstables and return whether all 
> data is readable all not. This should NOT care about consistency. 
> The compressed sstables do not have hash so not sure how it will work there.
