Duarte Nunes 8a90e242e4 Merge 'Fix misdetection of remote counter shards' from Paweł
"
The code reading counter cells form sstables verifies that there are no
unsupported local or remote shards. The latter are detected by checking
if all shards are present in the counter cell header (only remote shards
do not have entries there). However, the logic responsible for doing
that was incorrectly computing the total number of counter shards in a
cell if the header was larger than a single counter shard. This resulted
in incorrect complaints that remote shards are present.

Fixes #4206

Tests: unit(release)

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>
