C. Scott Andreas updated CASSANDRA-14751:
-----------------------------------------
    Component/s: Distributed Metadata

> Can't truncate counter CFs via Thrift
> -------------------------------------
>
>                 Key: CASSANDRA-14751
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14751
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Distributed Metadata
>         Environment: Cassandra 3.11.2
>            Reporter: Erik Swanson
>            Priority: Major
>
> When connecting to Cassandra 3.11.2 using Thrift, attempting to truncate a CF 
> with counters results in "invalid operation for commutative table [table 
> name]".
> It appears that there was no checking re this prior to the materialized views 
> work. The materialized views work added:
> {{CFMetaData metadata = ThriftValidation.validateColumnFamily(keyspace, 
> cfname, true);}}
> This was changed to `..., false);`  in 
> 3be99eeaa3546fecaf474d848eecca6aa0254a22, "ninja fix commutative op flag for 
> truncate validation", but that fix (allowing truncation of CFs that do not 
> include counters) breaks truncation of CFs that do contain counters.
> It's possible to truncate counter CFs via CQL, but that's no help re trying 
> to get an application that uses Thrift to work, which needs to be able to 
> truncate as part of its test suite.
> Because truncation via CQL works, or at least appears to work, would the 
> appropriate fix be to change CassandraServer.truncate to use this function on 
> ThriftValidation instead?:
> {{// To be used when the operation should be authorized whether this is a 
> counter CF or not}}
> {{public static CFMetaData validateColumnFamily(String keyspaceName, String 
> cfName) throws org.apache.cassandra.exceptions.InvalidRequestException}}
> {{{}}
> {{ return validateColumnFamilyWithCompactMode(keyspaceName, cfName, false);}}
> {{}}}
