[jira] [Created] (CASSANDRA-9816) ALTER TABLE ADD validation is
overly strict for re-added collection columns
Aleksey Yeschenko created CASSANDRA-9816:
--------------------------------------------
Summary: ALTER TABLE ADD validation is overly strict for re-added collection columns
Key: CASSANDRA-9816
URL: https://issues.apache.org/jira/browse/CASSANDRA-9816
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Priority: Minor
Fix For: 3.x
{{AlterTableStatement}} ensures that we cannot re-add a collection column of a type that is incompatible with a previously existing, dropped one.
It doesn't make an exception, however, for {{frozen}} collections, yet those should be allowed.
Code in question:
{code}
if (dropped != null && (dropped.type == null || (dropped.type instanceof CollectionType && !type.isCompatibleWith(dropped.type))))
throw new InvalidRequestException(String.format("Cannot add a collection with the name %s " +
"because a collection with the same name and a different type%s has already been used in the past",
columnName, dropped.type == null ? "" : " (" + dropped.type.asCQL3Type() + ")"));
{code}
