> Key: CASSANDRA-14871
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14871
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Core, Local/Compaction
> Reporter: Robert Stupp
> Assignee: Robert Stupp
> Priority: Urgent
> Fix For: 3.0.18, 3.11.4, 4.0
>
>
> There are a couple of places in the code base that do not respect that
> j.u.HashMap + related classes are not thread safe and some parts rely on
> internals of the implementation of HM, which can change.
> We have observed failures like {{NullPointerException}} and
> {{ConcurrentModificationException}} as well as wrong behavior.
> Affected areas in the code base:
> * {{SizeTieredCompactionStrategy}}
> * {{DateTieredCompactionStrategy}}
> * {{TimeWindowCompactionStrategy}}
> * {{TokenMetadata.Topology}}
> * {{TypeParser}}
> * streaming / concurrent access to {{LifecycleTransaction}} (handled in
> CASSANDRA-14554)
> While the patches for the compaction strategies + {{TypeParser}} are pretty
> straight forward, the patch for {{TokenMetadata.Topology}} requires it to be
> made immutable.
