Igniters,
Does anyone know the severity of this issue? In which cases is it reproduced? https://issues.apache.org/jira/browse/IGNITE-2008 In my view, we already have support for it, so it should be just a bug. Anyone knows how hard it is to fix? D. |
I played with this and it seems that locks are actually released when node
leaves, but lock futures that are waiting for this lock are never completed. Therefore, this issue can be workarounded by replacing lock() method with tryLock() in a loop. Anyone knows why this can happen? -Val On Wed, Dec 2, 2015 at 2:30 PM, Dmitriy Setrakyan <[hidden email]> wrote: > Igniters, > > Does anyone know the severity of this issue?

Val,
I think if lock futures are not complete, then the issue remains, because it can cause hanging clients. Did you get an idea of what it would take to fix it? D.

I fixed this issue with not release locks (
https://issues.apache.org/jira/browse/IGNITE-2008), fix will be available in 1.5 release.
