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

Formerly attached cassandra-5791.patch.txt creates invalid Digests for 
Uncompressed tables (related to #8778). Will modify the patch to separate the 
fix for #8778 from the rest of #5791



> A nodetool command to validate all sstables in a node

> 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.
