UnsupportedOperationException in system_update_column_family
------------------------------------------------------------
Key: CASSANDRA-1768
URL: https://issues.apache.org/jira/browse/CASSANDRA-1768
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.7.0
Reporter: T Jake Luciani
During testing I hit this section of code:
CFMetaData.java:662
{code}
// remove the ones leaving.
for (ByteBuffer indexName : toRemove)
column_metadata.remove(indexName);
{code}
but column_metadata is defined as:
{code}
this.column_metadata = Collections.unmodifiableMap(column_metadata);
{code}
So remove() will throw an exception.
{code}
java.lang.UnsupportedOperationException
