We have tried restarting couple of times and issue remains same so repointed to another node and able to communicate with db. We think some issue with this particular node only Regards, Srinivas Get Outlook for Android From: manish

Re: Issue with native protocol

Have you tried restarting your application? It should renegotiate the protoco during handshake and should resolve the issue. On Wed, Jul 28, 2021 at 3:06 PM Srinivas Polamarasetty < srinivas.polamarase...@logmein.com> wrote: > Query shows 4 but App team also getting below error. They were not

Re: High memory usage during nodetool repair

Based on the symptoms you described, it's most likely caused by SSTables being mmap()ed as part of the repairs. Set `disk_access_mode: mmap_index_only` so only index files get mapped and not the data files. I've explained it in a bit more detail in this article --

Re: [RELEASE] Apache Cassandra 4.0.0 released

If you're running Cassandra 3.x, the only data file requirement is that all SSTables present on your cluster are 3.x-era SSTables. This means that you should/should have run upgradesstables at least once on Cassandra 3.x after upgrading from an earlier release before upgrading to Cassandra

Re: [RELEASE] Apache Cassandra 4.0.0 released

Thanks Brandon! Anyone know the upgrade path from 3.x? https://cassandra.apache.org/doc/latest/cassandra/getting_started/installing.html Doesn't look like it has specific upgrade instructions. For instance do we need to run nodetool upgradesstables? TIA On 2021/07/26 20:03:59, Brandon

Re: cassandra 4.0 java 11 support

Anecdotally, I have no issues to report running Cassandra 4.0 on JDK11 and would be supportive of removing the "experimental" classification in an upcoming release. From: Erick Ramirez Sent: Tuesday, July 27, 2021 3:57 PM To: user@cassandra.apache.org

Re: Issue with native protocol

Someone asked me about the same issue a couple of months ago and we never managed to figure out why the wrong version is being displayed. Could you try to run `SELECT native_protocol_version FROM system.local`? It should come back with 4. Cheers!

Issue with native protocol

Team, We are having strange issue with one of Cassandra node in a cluster. All the nodes were connecting fine with native protocol version v4 but only 1 node is connecting to v3. Not sure, how can we fix the issue as all the config files were same across the cluster. Connected to
