> Issue when modifying UDT
> ------------------------
>
> Key: CASSANDRA-9148
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9148
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Oskar Kjellin
> Assignee: Benjamin Lerer
> Fix For: 2.1.5
>
>
> I'm trying out the user defined types but ran into some issues when adding a
> column to an existing type.
> Unfortunately I had to scrap the entire cluster so I cannot access it any
> more.
> After creating the UDT i adde two tables using it. 1 was just using
> frozen<type>. The other was using both frozen<type> frozen map<String, type>.
> Then I realized I needed to add a new field to the user type. Then when I
> tried to put to any of the two tables (setting all fields to the UDT in the
> datastax java driver) I got this error message that I could not find anywhere
> else but in the cassandra code:
> com.datastax.driver.core.exceptions.InvalidQueryException: Invalid remaining
> data after end of UDT value
> I had to scrap my keyspace in order to be able to use it again. Could not
> even drop one of the tables.
> I know that they are frozen so we cannot modify the value of individual
> fields once they are written but we must be able to modify the schema right?
