Max Schaefer created CASSANDRA-11660:
----------------------------------------
Summary: Dubious call to remove in CompactionManager.java
Key: CASSANDRA-11660
URL: https://issues.apache.org/jira/browse/CASSANDRA-11660
Project: Cassandra
Issue Type: Bug
Components: Compaction
Reporter: Max Schaefer
I'm surprised by
[this|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/compaction/CompactionManager.java#L1382]
call to {{Iterator.remove()}} in
{{org.apache.cassandra.db.compaction.antiCompactGroup}}: the iterator in
question seems to come from
[org.apache.cassandra.db.lifecycle.LifecycleTransaction.originals()|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/lifecycle/LifecycleTransaction.java#L419],
which returns an unmodifiable set, so I would expect this call to always fail
with an {{UnsupportedOperationException}}.
