When other bootstrapping/leaving/moving nodes are found during bootstrap, instead of throwing immediately, sleep and try again for one minute, hoping other nodes will finish the operation soon. This is useful when starting an empty cluster for testing. E.g, $ scylla --listen-address 127.0.0.1 $ scylla --listen-address 127.0.0.2 $ scylla --listen-address 127.0.0.3 Without this patch, node 3 will hit the check. TIME STATUS ----------------------- Node 1: 25:19 Starts 25:20 In NORMAL status Node 2: 25:19 Starts 25:23 In BOOT status 25:28 In NORMAL status Node 3: 25:19 Starts 25:24 Found node 2 in BOOT status, hit the check, sleep and try again 25:29 Found node 2 in NORMAL status, can keep going now 25:29 In BOOT status 25:34 In NORMAL status
#Scylla
##Building Scylla
In addition to required packages by Seastar, the following packages are required by Scylla.
Submodules
Scylla uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --recursive
Building and Running Scylla on Fedora
- Installing required packages:
sudo yum install yaml-cpp-devel lz4-devel zlib-devel snappy-devel jsoncpp-devel thrift-devel antlr3-tool antlr3-C++-devel libasan libubsan
- Build Scylla
./configure.py --mode=release --with=scylla --disable-xen
ninja build/release/scylla -j2 # you can use more cpus if you have tons of RAM
- 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>
