Tachyon on MapR 4.0.1

Hi,

Has anyone got Tachyon working with MapR v4.0.1? When trying to set the underfs as mapr:/// errors about an unsupported filesystem appear.

There are instructions about how to build it specifically for MapR here but they relate to MapR 4.0.0 FCS and not 4.0.1: https://github.com/amplab/tachyon/blob/master/docs/Building-Tachyon-Master-Branch.md

HDFS support seems to be built in, and pointing to MapR-FS/HDFS is needed for fault-tolerance as journal files need to be stored on the distributed filesystem so both master nodes can access this.

There are two topics I have found on this:

and

Cheers,
Mike
