Hello, I am looking to change how we trigger maintenance operations in our C* clusters. The end goal is to schedule and run the jobs using a system that is backed by Serf to handle the event propagation.
I know that when issuing some operations via nodetool, the command blocks until the operation is finished. However, is there a way to reliably determine whether or not the operation has finished without monitoring that invocation of nodetool? In other words, when I run 'nodetool repair' what is the best way to reliably determine that the repair is finished without running something equivalent to a 'pgrep' against the command I invoked? I am curious about trying to do the same for major compactions too. Cheers! -Tim
