Jeff Jirsa commented on CASSANDRA-5791:
---------------------------------------
So the same bug corrected in CASSANDRA-8778 was re-introduced by CASSANDRA-8709
, as it was developed in parallel and was likely merged/reviewed without the
benefit of knowing about #8778.
I've done the following:
1) Rebased to trunk as of 20150319
2) Removed o.a.c.io.DataIntegrityMetadata#append
3) Corrected o.a.c.io.DataIntegrityMetadata#appendDirect
4) Brought over [~benedict]'s PureJavaCRC32 's fix from above (which was
correct - 7bef6f93aea3a6897b53e909688f5948c018ccdf)

[~jbellis] and [~benedict] - if you want unit tests for DataIntegrityMetadata,
Jira it, assign me, and I'll write them. I'd have done it tonight but I can't
convince myself that they're not redundant with the (included) verifier unit
tests which will test the checksums anyway.

> 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.
