Subject Some giraph implementation questions..
Date Sun, 17 Jun 2012 05:54:04 GMT
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
