Re: Best approach to prepare to shutdown a cassandra node

Looking at the code in trunk, the stopdemon command invokes the CassandraDaemon.stop() function which does a graceful shutdown by stopping jmxServer and drains the node by the shutdown hook. On 10/20/17, Simon Fontana Oscarsson wrote: > Yes, drain will

Re: What is a node's "counter ID?"

I believe that’s just referencing a counter implementation detail. If I remember correctly, there was a fairly large improvement of the implementation of counters in 2.1, and the assignment of the id would basically be a format migration. > On Oct 20, 2017, at 9:57 AM, Paul Pollack

Re: Best approach to prepare to shutdown a cassandra node

Yes, drain will always be run when Cassandra exits normally. On 2017-10-20 00:57, Varun Gupta wrote: Does, nodetool stopdaemon, implicitly drain too? or we should invoke drain and then stopdaemon? On Mon, Oct 16, 2017 at 4:54 AM, Simon Fontana Oscarsson

Re: Not marking node down due to local pause

Hi John, the other main source of STW pause in the JVM is the safepoint mechanism : http://blog.ragozin.info/2012/10/safepoints-in-hotspot-jvm.html If you turn on full GC logging in your cassandra-env.sh file, you will find lines like this : 2017-10-09T20:13:42.462+: 4.890: Total time for

Lot of hints piling up

Hello, We have cassandra cluster in 3 regions with version 2.1.13, and all of a sudden we started seeing lot of hints accumulating on the nodes. We are pretty sure there is no issue with the network between the regions and all the nodes are up and running all the time. Is there any other reason

What is a node's "counter ID?"

Hi, I was reading the doc page for nodetool cleanup https://docs.datastax.com/en/cassandra/2.1/cassandra/tools/toolsCleanup.html because I was planning to run it after replacing a node in my counter cluster and the sentence "Cassandra assigns a new counter ID to the node" gave me pause. I can't
