Navjyot Nishant updated CASSANDRA-11063:
----------------------------------------
Description:
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.
