Asias He 71bf757b2c gossiper: Enable features only after gossip is settled
n1, n2, n3 in the cluster,

shutdown n1, n2, n3

start n1, n2

start n3, we saw features are enabled using the system table while n1 and n2 are already up and running in the cluster.

INFO  2019-02-27 09:24:41,063 [shard 0] gossip - Node 127.0.0.2 does not contain SUPPORTED_FEATURES in gossip, using features saved in system table, features={CORRECT_COUNTER_ORDER, CORRECT_NON_COMPOUND_RANGE_TOMBSTONES, COUNTERS, DIGEST_MULTIPARTITION_READ, INDEXES, LARGE_PARTITIONS, LA_SSTABLE_FORMAT, MATERIALIZED_VIEWS, MC_SSTABLE_FORMAT, RANGE_TOMBSTONES, ROLES, ROW_LEVEL_REPAIR, SCHEMA_TABLES_V3, STREAM_WITH_RPC_STREAM, TRUNCATION_TABLE, WRITE_FAILURE_REPLY, XXHASH}

The problem is we enable the features too early in the start up process.
We should enable features after gossip is settled.

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.

Note: GCC >= 8.1.1 is require to compile Scylla.

Note: See frozen toolchain for a way to build and run on an older distribution.

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>
