Change the IP of a live node

Hello, I am trying to change the IP of a live node (I am not replacing a dead one). So I stop the service on my node (not a seed node), I change the IP from 192.168.xx.xx to 10.179.xx.xx, and modify "listen_address" and "rpc_address" in the cassandra.yaml, while I also set auto_bootstrap: false.

Re: changing compaction strategy

Some more info: - running C* 3.9 - I tried `nodetool flush` on the column family this change applies to, and while it does seem to trigger compactions, there is still one pending that won't seem to run - I tried `nodetool compact` on the column family as well, with a similar affect Is there a way

Re: Change the IP of a live node

To give a complete picture, my node has actually two network interfaces: eth0 for 192.168.xx.xx and eth1 for 10.179.xx.xx On Tue, Mar 14, 2017 at 7:46 PM, George Sigletos wrote: > Hello, > > I am trying to change the IP of a live node (I am not replacing a dead > one). >

Re: COPY FROM performance

Launch cqlsh withe the "--debug" option: cqlsh --debug. You should see which Python driver it is using. My guess is that it is not using the installed driver, which by default should be Cythonized, but it is still using the embedded driver. This is what is shown on my machine for the embedded

I have similar question. when we create users or roles what is the consistency level used? I know, If NOT EXISTS will use SERIAL consistency. what consistency will be used if just use CREATE USER ? On Mon, Mar 13, 2017 at 7:09 PM, Jacob Shadix wrote: > I'm looking for a

Re: Does "nodetool repair" need to be run on each node for a given table?

For anyone with questions about how repair works, why repair, partial range repair, incremental vs. non-incremental repair, best practices for repair, etc. I highly recommend this talk from Alexander Dejanovski, The Last Pickle at Cassandra Summit 2016:

Re: HELP with bulk loading

Thank you all! It turns out that the fastest ways are: https://github.com/brianmhess/ cassandra-loader and COPY FROM. So I decided to stick with COPY FROM as it built-in and easy-to-use. On Fri, Mar 10, 2017 at 2:22 PM, Ahmed Eljami wrote: > Hi, > > >3. sstableloader is

COPY FROM performance

HI! I am trying to increase performance of COPY FROM by installing "*Cython and libev C extensions"* as described here: https://www.datastax.com/dev/blog/six-parameters-affecting-cqlsh-copy-from-performance . My steps are as the

Does "nodetool repair" need to be run on each node for a given table?

I understand that the nodetool command connects to a specific server and for many of the commands, e.g. "info", "compactionstats", etc, the information is for that specific node. While for some other commands like "status", the info is for the whole cluster. So is "nodetool repair" that

Hi all, We are using a C* 2.2.8 cluster in our production system, composed of 5 nodes in 1 DC with RF=3. Our clients mostly write with CL.ALL and read with CL.ONE (both will be switched to quorum soon). We face several problems while trying to persist classical "follow relationship". Did anyone

Am I unreasonable in expecting a poster to have looked at the documentation before posting? And that reposting the same query WITHOUT reading the documents (when pointed out to them) when asked to do so is not appropriate? Do we have a way to blackball such? *...* *Daemeon C.M.
