Andrzej Bialecki commented on SOLR-13140:
------------------------------------------
bq. ... can you please clarify what you mean by "a (currently unsupported)
DELETENODE request" ?
Sorry, please ignore that part - I mixed this up with another operation. This
is definitely supported (via {{DeleteNodeSuggester}}.
bq. Unless the underlying Collections API impl of DELETENODE is smart enough
not to shutdown a leader (or the last remaining replica) this definitely seems
like a bug.
Correct, it's a bug - {{SearchRateTrigger.calculateColdOps}} has a section at
the end when {{belowNodeOp != null}} and there it should protect leader nodes
from being deleted. There's also a non-javadoc comment there about the dangers
of this functionality, which is also mentioned in the Ref Guide (but perhaps
should be turned into a NOTE?).
