Asias He ad656b2c55 storage_service: Do not wait for restore_replica_count in handle_state_removing
The call chain is:

storage_service::on_change() -> storage_service::handle_state_removing()
-> storage_service::restore_replica_count() -> streamer->stream_async()

Listeners run as part of gossip message processing, which is serialized.
This means we won't be processing any gossip messages until streaming
completes.

In fact, there is no need to wait for restore_replica_count to complete
which can take a long time, since when it completes, this node will send
notification to tell the removal_coordinator that the restore process is
finished on this node. This node will be removed from _replicating_nodes
on the removal_coordinator.

Tested with update_cluster_layout_tests.py

Fixes #2886

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>
