1. Is it the master who ensures that sendToNeighbours() call actually succeeds Or it is entirely done by the underlying hadoop RPC ?
2. Is it possible that a single errant worker ( hadoop mapper ) can delay the completion of a single superstep ? 3. While running giraph I saw 1 master_zookeper and 3 workers. Does it mean that in default config zookeper runs on master mapper ? -Thanks, Prasenjit
