nodetool disablehintsfordc

Where is the cassandra-env.sh file located?

The location of the cassandra-env.sh file depends on the type of installation:

Package installations and installer-services installations: /etc/dse/cassandra/cassandra-env.sh
Tarball installations and installer-no services installations: INSTALLATION_LOCATION/resources/cassandra/conf/cassandra-env.sh

Disable hints for a datacenter.

Synopsis

nodetool [options] disablehintsfordc [--] <datacenter>

Tarball and Installer No-Services path:

<installation_location>/resources/cassandra/bin

Connection options
Short	Long	Description
`-h`	`--host`	Hostname or IP address.
`-p`	`--port`	Port number.
`-pwf`	`--password-file`	Password file path.
`-pw`	`--password`	Password.
`-u`	`--username`	Remote JMX agent username.
datacenter	The datacenter to disable.
`--`	Separates an option from an argument that could be mistaken for an option.

For tarball installations, execute the command from the <installation_location>/bin directory.
If a username and password for RMI authentication are set explicitly in the cassandra-env.sh file for the host, then you must specify credentials.
nodetool disablehintsfordc operates on a single node in the cluster if -h is not used to identify one or more other nodes. If the node from which you issue the command is the intended target, you do not need the -h option to identify the target; otherwise, for remote invocation, identify the target node, or nodes, using -h.
[--] can be used to separate command-line options from the list of arguments, when the list might be mistaken for options.

The nodetool disablehintsfordc command is used to turn off hints for a datacenter. This can be useful if there is a downed datacenter, but hints should continue on other datacenters. Another common case is during datacenter failover, when hints put unnecessary pressure on the datacenter.
