" This is a backport of CASSANDRA-8236. Before this patch, scylla sends the node UP event to cql client when it sees a new node joins the cluster, i.e., when a new node's status becomes NORMAL. The problem is, at this time, the cql server might not be ready yet. Once the client receives the UP event, it tries to connect to the new node's cql port and fails. To fix, a new application_sate::RPC_READY is introduced, new node sets RPC_READY to false when it starts gossip in the very beginning and sets RPC_READY to true when the cql server is ready. The RPC_READY is a bad name but I think it is better to follow Cassandra. Nodes with or without this patch are supposed to work together with no problem.

Scylla
Quick-start
$ git submodule update --init --recursive
$ sudo ./install-dependencies.sh
$ ./configure.py --mode=release
$ ninja-build -j4 # Assuming 4 system threads.
$ ./build/release/scylla
$ # Rejoice!
Please see HACKING.md for detailed information on building and developing Scylla.
Running Scylla
- Run Scylla
./build/release/scylla
- run Scylla with one CPU and ./tmp as data directory
./build/release/scylla --datadir tmp --commitlog-directory tmp --smp 1
- For more run options:
./build/release/scylla --help
Building Fedora RPM
As a pre-requisite, you need to install Mock on your machine:
# Install mock:
sudo yum install mock
# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock
Then, to build an RPM, run:
./dist/redhat/build_rpm.sh
The built RPM is stored in /var/lib/mock/<configuration>/result directory.
For example, on Fedora 21 mock reports the following:
INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result
Building Fedora-based Docker image
Build a Docker image with:
cd dist/docker
docker build -t <image-name> .
Run the image with:
docker run -p $(hostname -i):9042:9042 -i -t <image name>
