"gossiping_property_file_snitch checks its property file (cassandra-rackdc.properties) for changes every minute and if there were changes it re-registers the helper and initiates re-read of the new DC and Rack values in the corresponding places. Therefore we need the ability to unregister/register the corresponding subscriber at the same time when a subscriber list is possibly iterated by some other asynchronous context on the current CPU. The current gossiper implementation assumes that subscribers list may not be changed from the context different from the one that iterates on their list. So, this had to be fixed. There was also missing an update_endpoint(ep) interface in the locator::topology class and the corresponding token_metadata::update_topology(ep) wrapper. Also there were some bugs in the gossiping_property_file::reload_configuration() method."
#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 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
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>
