Benjamin Lerer commented on CASSANDRA-16259:
--------------------------------------------
Sorry, I am sick since a couple of day and do not have the energy to dig into
the code.
If I am not mistaken the problem can be solve by triggering an index summary
redistribution using JMX ({{IndexSummaryManager.redistributeSummaries()}}). See
CASSANDRA-5519 for a better understanding of the impact.
Hope it help.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-16259
> Project: Cassandra
> Issue Type: Bug
> Components: Observability/Metrics
> Reporter: Justin Montgomery
> Assignee: Benjamin Lerer

> After upgrading some nodes in our cluster from 3.11.8 to 3.11.9 an error
> appeared on the upgraded nodes when trying to access *tablehistograms*. The
> same command run on our .8 nodes return as expected, only the upgraded .9
> nodes fail. Not all tables fail when queried, but about 90% of them do.
> We use Datastax MCAC which appears to query histograms every 30 seconds, this
> outputs to the system.log:
