Subject Re: Cache atomic conditional remove returns error when node leaves cluster
Date Sat, 16 Apr 2016 04:40:32 GMT
Hi,

This is possible in ATOMIC cache, because if the client doesn't receive the
response from the failed node, it doesn't know if the value was removed or
not. It will then get an exception and retry, but if the value was removed
on the first iteration, false will be removed.

Can you try switching to TRANSACTIONAL cache [1]? It guarantees strict
semantics and should fix your case.
