Asias He 3c8ed255ac storage_service: Set NORMAL status after token_metadata is replicated
Commit 2d5fb9d109 (gms/gossiper: Replicate changes incrementally to
other shards) changes the way we replicate _token_metadata and
endpoint_state_map. Before they are replicated at the same time, after
they are not any more. This causes a shard in NORMAL status can still be
with a empty _token_metadata.

We saw errors:

   [shard 12] token_metadata - sorted_tokens is empty in first_token_index!

during CorruptThenRepairNemesis.

Fix by setting the gossip status to NORMAL after replication of
_token_metadata, so that once a node is in NORMAL, we can do repair. The
commit 69c81bcc87 (repair: Do not allow repair until node is in NORMAL
status) prevents the early repair operation by checking if a node is in
NORMAL status.

Fixes #3121

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>
