title: Apache Cassandra : Hints are getting created continuosly even if all the nodes are up
body: <p>I have a 5 node apache cassandra 2.0.6 cluster with 48 GB ram and 2 TB data directory and commit log directory with 93 GB capacity. The JVM heap space for cassandra is 8 GB. I use JVisualVM Mbeans plugin for monitoring the cassandra metrics. The hints are getting created continuously in all nodes even though all the nodes are up. And as hints are getting created while writing data, after sometime i am facing tombstone overwhelming exception which is aborting the queries. Could anyone please explain why is it happening and provide remedy for the same. </p>
