spark-ec2 script with Tachyon

[nit <ni...@gmail.com>]

Hi,

It seems that spark-ec2 script deploys Tachyon module along with other
setup.
I am trying to use .persist(OFF_HEAP) for RDD persistence, but on worker I
see this error
--
 Failed to connect (2) to master localhost/127.0.0.1:19998 :
java.net.ConnectException: Connection refused
--

>From netstat I see that worker is connected to master node on port 19998

Does Tachyon on EC work out of the box? or does it requite further
configuration ?

Am I supposed to set  "spark.tachyonStore.url" to Masters IP ?

Did you manage to figure this out? I would appreciate if you could share the
