Subject Master to Wake Up All Vertices
Date Tue, 12 Mar 2013 16:57:32 GMT
Hi All,

Currently in my project, the master has to wake up all halted vertices
when certain conditions are met. To do this I actually hacked a little
bit of org.apache.giraph.graph.ComputeCallable.computePartition. So
that the computing thread can read a special aggregator set up by the
master and then decide whether all the halted vertices should be woken
up. Is there any neater approach for doing it? Or, if there isn't,
should we implement such method?
