Restarting a cluster
Restart an entire cluster. Each node in the cluster restarts in a sequential rolling fashion after a sleep time elapses.
Restart an entire cluster. Each node in the cluster restarts in a sequential rolling fashion after a sleep time elapses. Optionally, drain each node before stopping and restarting each node in the cluster. Some operations such as changing configurations prompt you to perform a rolling restart.
You can override the default value of
the rolling_restart_error_threshold
configuration option in
cluster_name.conf. The threshold value represents
the number of errors tolerated during a rolling restart before canceling the
restart. The default value is 1. See Cassandra
connection properties for more information.
cluster_name.conf
The location of the cluster_name.conf file depends on the type of installation:
- Installer-Services or package installations: /etc/opscenter/clusters/cluster_name.conf
- Installer-No Services or tarball installations: install_location/conf/clusters/cluster_name.conf
- Windows installations: Program Files (x86)\DataStax Community\opscenter\conf\clusters\cluster_name.conf
