[jira] [Comment Edited] (CASSANDRA-13043) Unable to achieve CL
while applying counters from commitlog
[ https://issues.apache.org/jira/browse/CASSANDRA-13043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16048886#comment-16048886 ]

-----------------------------------------------------------------------
Update: turned out the commitlog was a false flag. On all other nodes where I found this issue I had no replayed mutations.
The missed QUORUMs were client requests being served before the node had full visibility over the cluster.
However, there two things that are weird:
1) It's always about a counter mutation (and the distribution of queries is heavily skewed in favour of non-counter queries).
2) The exception happens while the node is updating the topology and before the gossip settles (which is weird since I thought client requests were not allowed until then.

> In version 3.9 of Cassandra, we get the following exceptions on the system.log whenever booting an agent. They seem to grow in number with each reboot. Any idea where they come from or what can we do about them? Note that the cluster is healthy (has sufficient live nodes).
