C. Scott Andreas updated CASSANDRA-14998:
-----------------------------------------
    Component/s: Tool/bulk load

> Support "validate only" option for `nodetool import`
> ----------------------------------------------------
>
>                 Key: CASSANDRA-14998
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14998
>             Project: Cassandra
>          Issue Type: New Feature
>          Components: Tool/bulk load
>            Reporter: Doug Rohrer
>            Priority: Major
>
> In order to support safer import of data (especially in the face of nodetool 
> import now taking multiple directories as input completed in 
> CASSANDRA-14442), it would be good to be able to validate said data before 
> import as it is possible one or more SSTables may somehow have been corrupted 
> during transport. I'm not sure what the preferred way forward on this (add a 
> `nodetool verify-import` or perhaps `nodetool import --verify-only` as a 
> flag) but this would allow an end-user to prevent partial imports where some 
> of the data is good, and some is corrupt.
