As Ethiopian is now officially part of Star Alliance, they have published both the earnings and award chart for Star Alliance partners.
The earning can be found here:

IMHO the award rules make very little sense. You are only allowed a one direct flight each way or you need to use multiple awards.
Segment
Specific awards are assigned to round trips and one way. Round trip applies to 2 segments flights. One way applies to 1 segment flight.
Specific Award Rules
Miles indicated in the chart are good for Award Ticket redemption. It applies to round trip. The most direct flights between the origin airport and the destination airport should apply. Only one flight is allowed in each direction. Any other routing will require combining two or more Awards in order to fulfill a redemption request.
One way award is 75 percent of the round trip mile requirement.
There may be restriction on Award Application for certain flights and airlines on some routes.
More than one Star Alliance member airlines flights can be combined on one award ticket.
Code share flights should be booked on the operating airline flight number.
First Class and Business Class Flights awards cannot be used on Singapore Airlines flights operated by A380, A345, and B777-300ER aircrafts.
There are some periods when Award Tickets cannot be used on Star Alliance Member Airlines Flights. Seats for flights are subject to availability at all times. Seats may not be available for awards even if seats are available for paid tickets.
Award tickets are ineligible for mile accrual.
