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

             Summary: Hinted Handoff: java.lang.ArithmeticException: / by zero
                 Key: CASSANDRA-7456
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7456
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: 2.0.6
            Reporter: sankalp kohli
            Priority: Minor


We are seeing this exception. This is similar to CASSANDRA-5990 but here the 
exception is coming because hintStore.getMeanRowSize() is returning zero i 
think. This is blowing up in 
return Math.max(2, Math.min(PAGE_SIZE, 
DatabaseDescriptor.getInMemoryCompactionLimit() / averageColumnSize));
