Parallel Reader fail on command line

I am trying to run a graph from command line. The graph uses PARALLEL_READER component to read some csv files. I followed following steps:

1. Set CLOVER_HOME
2. navigate to project folder
3. run graph

It throws following exception:

Unknown component: PARALLEL_READER class: PARALLEL_READER
