-------------------------------------------------
Summary: Forward slash in role name breaks CassandraAuthorizer
Key: CASSANDRA-14088
URL: https://issues.apache.org/jira/browse/CASSANDRA-14088
Project: Cassandra
Issue Type: Bug
Components: Auth
Environment: Git commit: 4c80eeece37d79f434078224a0504400ae10a20d
(`HEAD` of `trunk`).
Reporter: Jesse Haber-Kucharsky
Priority: Minor
The standard system authorizer
(`org.apache.cassandra.auth.CassandraAuthorizer`) stores the permissions
granted to each user for a given resource in `system_auth.role_permissions`.
A resource like the `my_keyspace.items` table is stored as
`"data/my_keyspace/items"` (note the `/` delimiter).
Similarly, role resources (like the `joe` role) are formatted as `"roles/joe"`.
The problem is that roles can be created with `/` in their names, which
confuses the authorizer when the table is queried.
For example,
```
$ bin/cqlsh -u cassandra -p cassandra
