Andrew Mashenkov commented on IGNITE-9053:
------------------------------------------
[~avinogradov]
As far as I understand, the main issue here is Discovery thread stucks on
removeExplicitNodeLocks and CQProcessor listener has got no node left event.
If it's so, I believe removing locks in async way should resolve this issue.
Please, take a look at IGNITE-9290.
