Jonathan Ellis commented on CASSANDRA-3596:
-------------------------------------------
... So the fix is to add support for replicate_on_write to CQL, not to band-aid
it in cqlsh.
> cqlsh: DESCRIBE output for a columnfamily does not work as input to same C*
> instance

> Key: CASSANDRA-3596
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3596
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Affects Versions: 1.0.3
> Environment: Cqlsh running against a recent Cassandra build
> Reporter: paul cannon
> Assignee: paul cannon
> Priority: Minor
> Labels: cqlsh
> Fix For: 1.0.6

> The {{DESCRIBE COLUMNFAMILY}} cqlsh command produces output that is intended
> to be usable as valid CQL (at least, when given to another Cassandra instance
> of the same version). But the output yields errors when run:
> {noformat}
> cqlsh> USE blah;
> cqlsh:blah> CREATE COLUMNFAMILY cf1 (c1 int PRIMARY KEY, c2 varchar);
> cqlsh:blah> DESCRIBE COLUMNFAMILY cf1;
> CREATE COLUMNFAMILY cf1 (
> c1 int PRIMARY KEY,
> c2 text
> ) WITH
> comment='' AND
> comparator=text AND
> row_cache_provider='ConcurrentLinkedHashCacheProvider' AND
> key_cache_size=200000.000000 AND
> row_cache_size=0.000000 AND
> read_repair_chance=0.100000 AND
> gc_grace_seconds=864000 AND
> default_validation=text AND
> min_compaction_threshold=4 AND
> max_compaction_threshold=32 AND
> row_cache_save_period_in_seconds=0 AND
> key_cache_save_period_in_seconds=14400 AND
> replication_on_write=True;
> cqlsh:blah> CREATE COLUMNFAMILY cf1 (
> ... c1 int PRIMARY KEY,
> ... c2 text
> ... ) WITH
> ... comment='' AND
> ... comparator=text AND
> ... row_cache_provider='ConcurrentLinkedHashCacheProvider' AND
> ... key_cache_size=200000.000000 AND
> ... row_cache_size=0.000000 AND
> ... read_repair_chance=0.100000 AND
> ... gc_grace_seconds=864000 AND
> ... default_validation=text AND
> ... min_compaction_threshold=4 AND
> ... max_compaction_threshold=32 AND
> ... row_cache_save_period_in_seconds=0 AND
> ... key_cache_save_period_in_seconds=14400 AND
> ... replication_on_write=True;
> Bad Request: replication_on_write is not a valid keyword argument for CREATE
> COLUMNFAMILY
> {noformat}
> So it needs to do a better job of determining which CF attributes are valid
> for which C* versions.
