Restoring passing schema fails #6

Hi Maor,

Trying to restore passing the schema argument but it seems that cain searches for an nonexisting s3 path (schema.cql/schema.cql):

 $ cain restore --src 's3://db-backup/cassandra/default/thingsboard' -n default -k keyspace1 -l app=cassandra -t 20181228214738 --schema schema.cql
2018/12/28 21:55:17 Restore started!

Hi,

The --schema flag takes a schema version (shortened sum). Look under s3://db-backup/cassandra/default/thingsboard/<schemaHash>

So you would need to use --schema <schemaHash>.

My bad, passing the schema hash it works. You can close this one.
