By default the value is 90 as per, any particular reason to chase extra 9%

yes, it's because I bump into it all the time: I believe other developers like me are also fine with spending most of their time with 90+ percent full disk without bumping into issues like this, 99% is the upper limit I consider serious (at that level, my laptop also starts to warn about disk space)

(bumping into it all the time, I mean: TEZ-4366, TEZ-4123)

Please rerun the CI as there are UT failures .
