Error while building master-branch: MatrixFactorizationModel.scala:19: object r is not a member of package tachyon

[zarzen]

Hi, I am building master branch. I have installed tachyon using install_tachyon.sh. While building velox-modelserver with command mvn package it raises a lot of errors related to one class, ClientStore, which imported through import tachyon.r.sorted.ClientStore. Here is the errors:

I am confused that tachyon doesn't contain package r.sorted and I haven't found type ClientStore either in project tachyon or velox-modelserver.
