nodetool disablehintsfordc

Disable hints for a datacenter.

The location of the file depends on the type of installation:

Package installations
Installer-Services installations


Tarball installations
Installer-No Services installations


Disable hints for a datacenter.


nodetool [options] disablehintsfordc [--] <datacenter>
Tarball and Installer No-Services path:
Table 1. 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 a 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 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 will put unnecessary pressure on the datacenter.
