Subject [jira] [Commented] (CASSANDRA-5791) A nodetool command to validate all sstables in a node
Date Fri, 06 Dec 2013 13:28:36 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13841241#comment-13841241

Radovan Zvoncek commented on CASSANDRA-5791:
--------------------------------------------

Once CASSANDRA-4165 gets solved, it might be quite neat to reuse the upgradesstables code
to iterate over stables. This way we'd only need to add verifying the digests. As long as
nobody is currently looking into this, I'd like to give it a shot.

> 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.
