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.
Description
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.
Examples
$ nodetool -u username -pw password disablehintsfordc DC2
