I suggest (based on input from @benjaminhindman) we don't use a specific constant here, but try using CHECK_DOUBLE_EQ, first. Only if this does not work, we should switch to CHECK_NEAR, which takes epsilon as an argument. (In that case, we'd have to elevate the constant to a more prominent place and describe it in the docs as well.) With either of this, we'll have a viable short-term fix. The long-term solution will be pursued by MESOS-3997. - Bernd ----------------------------------------------------------- This is an automatically generated e-mail.
