    [ https://issues.apache.org/jira/browse/CASSANDRA-15159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16863699#comment-16863699 ] 

Laxmikant Upadhyay commented on CASSANDRA-15159:
------------------------------------------------

This issue is not related to CASSANDRA-12765 as the sstable with tombstone does not have maxLocalDeletionTime == Integer.MAX_VALUE.

> In 3 node Cassandra cluster, one node has old mutation and two nodes have evict-able (crossed gc grace period) tombstone produced by TTL. A read query with local quorum return the old mutation as result when one request goes to the node having old mutation. However expected result should be empty. 
> Attached the steps to reproduce and trace of read query.
