-------------------------------------------

             Summary: Unable to compute ceiling for max when histogram overflowed
                 Key: CASSANDRA-11063
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11063
             Project: Cassandra
          Issue Type: Bug
          Components: Compaction
         Environment: Cassandra 2.1.9 on RHEL
            Reporter: Navjyot Nishant


Issue https://issues.apache.org/jira/browse/CASSANDRA-8028 seems related with error we are getting. But we are getting this with Cassandra 2.1.9 when autocompaction is running it keeps throwing following errors, we are unsure if its a bug or can be resolved, please suggest.
