Subject Automating nodetool repair
Date Mon, 27 Aug 2012 23:52:51 GMT
Hi all,
So nodetool repair has to be run regularly on all nodes. Does anybody 
have any interesting strategies or tools for doing this or is everybody 
just setting up cron to do it?

For example, one could write some Puppet code to splay the cron times 
around so that only one should be running at once.
Or, perhaps, a central orchestrator that is given some known quiet time 
and works its way through the list, running nodetool repair one at a 
time (using RPC?) until it runs out of time.
