yaml_diff

Using the yaml_diff to compare the differences between specified cassandra.yaml or dse.yaml files.

dse.yaml

The location of the dse.yaml file depends on the type of installation:
Package installations /etc/dse/dse.yaml
Tarball installations installation_location/resources/dse/conf/dse.yaml

cassandra.yaml

The location of the cassandra.yaml file depends on the type of installation:
Package installations /etc/dse/cassandra/cassandra.yaml
Tarball installations installation_location/resources/cassandra/conf/cassandra.yaml

The yaml_diff compares the differences between specified cassandra.yaml or dse.yaml files.

The default location of the yaml comparison tool depends on the type of installation:
  • Package installations: /usr/share/dse/tools/yamls
  • Tarball installations: install_location/tools/yamls
Before comparing the yaml files, install PyYAML:
sudo pip install pyyaml
