Seems to be flaky/failing recent release branch failure

[gjoliver]

this is known to be flaky. a few folks took a look and couldn't really understand this. I am gonna assign this to Sven for help.

[rickyyx]

But this is still considered a release blocker right?

[gjoliver]

this is not blocking. it's a weird flakiness for an unimportant algorithm that has been there for a long time. I have taken off the blocker label and made this a RLlib P0.

[kouroshHakha]

yes not release blocker. R2D has been flakey from the get go. We have kept it in so that maybe we get the time to look at it later. We should make this P1 also.
