shark not able to connect to spark master

danoomistmatiste
Hi, I have installed spark0.8.1-incubating.  Both my master and worker processes are running. Master is listening on port 7077.  I have also installed shark (0.8.0).  When I try to start the shark shell (./shark-withinfo),  I get this exception,

14/01/07 21:49:21 INFO client.Client$ClientActor: Connecting to master spark://localhost:7077
shark> 14/01/07 21:49:21 ERROR client.Client$ClientActor: Connection to master failed; stopping client
14/01/07 21:49:21 ERROR cluster.SparkDeploySchedulerBackend: Disconnected from Spark cluster!
