(resending...) I was thinking the same setup… But the more I think of this problem, and the more interesting this could be. If we allocate 50% total memory to Tachyon statically, then the Mesos benefits of dynamically scheduling resources go away altogether. Can Tachyon be resource managed by Me

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I am fairly new to the spark ecosystem and I have been trying to setup a spark on mesos deployment. I can't seem to figure out the "best practices" around HDFS and Tachyon. The documentation about Spark's data-locality section seems to point that
