Hi, Ranga

That's true. Typically a version mis-match issue. Note that spark 1.2.1 has tachyon built
in with version 0.5.0 , I think you may need to rebuild spark 
with your current tachyon release. 
We had used tachyon for several of our spark projects in a production environment.

Subject: StorageLevel: OFF_HEAP

I am trying to use the OFF_HEAP storage level in my Spark (1.2.1) cluster. The Tachyon (0.6.0-SNAPSHOT)
nodes seem to be up and running. However, when I try to persist the RDD, I get the following

ERROR [2015-03-16 22:22:54,017] ({Executor task launch worker-0}[connect]:364)
 - Invalid method name: 'getUserUnderfsTempFolder'
ERROR [2015-03-16 22:22:54,050] ({Executor task launch worker-0}[getFileId]:1020)
 - Invalid method name: 'user_getFileId'

Is this because of a version mis-match? 

On a different note, I was wondering if Tachyon has been used in a production environment
by anybody in this group? 

Appreciate your help with this.
