Sergey Shelukhin commented on HIVE-14740:
-----------------------------------------
There seem to be 3 things... node set from which dead nodes should be removed
but aren't. Active instance set, that was only used in specific-node
scheduling, but not in random scheduling, until recently. And then there's
isAlive.
I wonder if so many ways to find if node is alive are needed.
> LLAP DynamicServiceInstasnce.isAlive does not seem to work as it should
