Bartłomiej Romański commented on CASSANDRA-4417: ------------------------------------------------ And the last comment. Could this be related to: CASSANDRA-4071? If I understand the description correctly any topology changes (adding a node, moving a node) when the counter is spread across more than one sstable can result in the "invalid counter shard detected" error message during reads.
